addict working in a hospital may have put 3,000 patients at risk of hepatitis and h.i.v. and norma at 90 having the time of her life. captioning sponsored by cbs this is the "cbs evening news" with scott pelley. >> pelley: today president obama said his supreme court nominee would head to capitol hill for meetings tomorrow, but hours later senate republican leader mitch mcconnell phoned nominee merrick garland to say, don't bother coming. i won't meet with you and the senate won't act on your nomination. the president named garland, a liberal to, replace the late conservative justice antonin scalia. garland is chief judge on what's considered to be the second most powerful court in the land, the washington, d.c., circuit court of appeals. he was appointed by president clinton.

harvard law. here's chief legal correspondent jan crawford. >> today i am not indicating chief judge merrick brian garland to join the supreme court. [applause] >> reporter: his experience as a federal appellate judge is deep. his credentials unquestioned. but the president today said what sets garland apart is his temperament. >> to find someone who just about everyone not only respects but genuinely likes, that is rare. >> reporter: garland seemed a long shot, the oldest nominee in modern history, he's been on the short list for previous vacancies and passed over. today, finally, was garland's moment. >> this is the greatest honor of my life other than my wife agreeing to marry me 28 years ago. >> reporter: his wife and one of his daughters were among more than 100 supporters in the rose garden. >> i only wish my father were here to see this today.

taught my older daughter to be so adventurous that she would be hiking in the mountains out of cell service range. [laughter] when the president called. >> reporter: garland joined the federal appeals court in 1997. he's considered a moderate liberal who builds consensus. before becoming a judge, he spent much of his life in public service. his tenure at the justice department was defining. he supervised the prosecution of the 1995 oklahoma city bombing. >> we promised that we would find the perpetrators, that we would bring them to justice and that we would do it in a way that honored the constitution. >> reporter: he says that's at the core of his beliefs. >> fidelity to the constitution and the law has been the cornerstone of my professional life. if the senate sees fit to confirm me to the position for which i have been nominated

that course. >> reporter: now garland obviously does not bring diversity to the court. he would be yet another justice who went to law school at harvard or yale. with a rough senate fight ahead, the president said he was focused on qualifications. >> pelley: jan crawford for us at the court this evening. jan, thank you. as we said, that fight appears to be over before it began. here's margaret brennan. >> i simply ask republicans in the senate to give him a fair hearing and then an up-or-down vote. if you don't, it will not only be an abdication of the senate's constitutional duty, it will indicate a process for nominating and confirming judges that is beyond repair. >> let's let the american people decide. >> reporter: within minutes republican majority leader mitch mcconnell said no, congress will wait until a newly elected president picks a supreme court justice. >> our view is this: give the people a voice in filling this

>> reporter: mcconnell pointed to then-senator joe biden's recommendation to president bush back in 1992. >> once the political season is under way, and it is, action on a supreme court nomination must be put off until after the election campaign is over. >> reporter: but the white house thinks the american public is on its side and hopes garland's sterling legal credentials and moderate political record will persuade some republicans. president obama singled out senator orrin hatch, one of seven sitting republicans, who backed garland's 1997 nomination to the d.c. circuit. >> i believe mr. garland is a fine nominee. i know him personally. i know of his integrity. i know of his legal ability. i know of his honesty. i know of his acumen, and he belongs on the court. >> reporter: hatch said today that times have changed. >> there is a world of a difference between being on any circuit court of appeals and being a nominee for the supreme court of the united states when you have ultimate

>> reporter: and a handful of senate republicans have agreed to meet with garland, and senate judiciary committee chairman chuck grassley said he'll consider it. scott, this is a political gamble. republicans want to appear strong but not obstructionist, which could ultimately backfire to the benefit of democrats. >> pelley: margaret brennan at the white house tonight. margaret, thank you. well, the presidential election overshadows this supreme court battle, and last night republican front-runner donald trump won at least three more contests. the states in orange are trump's wins to date. blue are ted cruz. two-term governor john kasich won his first and only primary last night, his home state ohio. but apparently the show-me state, missouri, didn't see enough. last night they cast 1.5 million votes, and both trump and cruz and clinton and sanders are separated by less than 2,000

official result yet. even so, cbs news estimates that trump now has more than half the delegates he needs for the nomination. here's major garrett. >> this was an amazing evening. love you. split decision whittled the field to throw candidates. >> we are on the right side this year, but we will not be on the winning side. >> reporter: after losing in his home state, marco rubio dropped out. trump is on pace the win, but ted cruz and john kasich said they'll fight for delegates until the end. >> only two campaigns have a plausible path to the nomination, ours and donald trump's. nobody else has any mathematical possibility whatsoever. >> it is unlikely that anybody is going to achieve enough tell gaza city to avoid a convention. >> reporter: the g.o.p. front-runner mentioned this

doesn't get the nomination at a contested convex. >> i don't think you can say we get it automatically. i think you'd have riots. >> reporter: this morning john boehner floated another idea, draft current speaker paul ryan. his spokeswoman shot that down quickly saying, he will not accept a nomination. and republican national committee chairman reince preibus told us there won't be a need for a new candidate. >> there isn't going to be some sort of game played where someone goes into the convention with a majority of the delegates and somehow or another that person is not the nominee. i don't see that happening. >> reporter: but delegates are only bound to their candidates for the first ballot, and preibus acknowledged the party can rewrite the convention rules at its discretion. >> i would imagine the nomination rules would have to be looked at because obviously you'd have second and third ballot-type rules that you wouldn't have contemplated in the last convention. >> reporter: the now three-man race was headed for a prime time debate monday, but trump and kasich pulled out, forcing its cancellation.

the night before a contest in utah and arizona with 98 delegates at stake. >> pelley: major garrett, thanks. you probably remember the tense moment on saturday when man rushed donald trump. well, today that man, thomas dimassimo, was charged with a federal crime -- entering a secret service restricted area. now to the democrats. hillary clinton won at least four more states last night. she now has nearly two-thirds of the delegates that she needs for the nomination. here's nancy cordes. >> thank you, florida. thank you, north carolina. thank you, ohio. >> reporter: clinton had more thanking to do than her own campaign had expected. she swept four states by as much as 31 points, a feat sanders did not acknowledge at his rally in phoenix. >> next week arizona has a very important election.

the vermont senator insisted he is still on path to win the nomination and that the primary calendar favors us in the weeks and months to come. but that's also what he said before last nation's blowout. >> crowd: hillary! hillary! >> reporter: in a memo today, the clinton campaign laid out the odds against sanders. nearly half of the remaining delegates are in just throw states, california, new york and pennsylvania. senator sanders would have to win them by 20 points and rack up a string of victories just to pull even. in short, they argued, clinton's delegate lead is now nearly insurmountable. >> we are moving closer to securing the democratic party nomination and winning this election in november. [cheering and applause] >> reporter: the clinton camp knows there is a fine line between confidence and arrogance. they say they will not be calling on sanders to drop out, that it's entirely his decision

summer choice back in 2008, clinton stayed in all the way until the end. >> pelley: nancy cordes, thanks. now, with confidence and not a hint of arrogance, we will turn to john dickerson, our cbs news political director and the anchor of "face the nation." john, trump lost a big one in ohio last night. how damaging was that? >> reporter: well, not winning those 66 delegates means trump has to do better in the future. before last night he had won 44% of the delegates. now he needs to win 52% of the remaining delegates up for grabs, but rules in later contests give win ears greater share of the delegates. and that will help him. and there was evidence last night, particularly in florida, where he got 48% of the vote, that his results improve as the field shrinks. so he has shown the capacity to do better in the future. >> pelley: now, if republicans wanted to deny trump the nomination, is there a way they could do that in the coming contests? >> they have to win enough delegates to deny him the

means beating him outright in the states where there are winner-take-all, where he might be weak, states like montana, nebraska and south dakota. then in states where he's strong that distribute delegates from portion natalie, his proponents have to come in a close second to that -- to shrink his delegate surprise, but that's hard to do because kasich and cruz keep splitting the non-trump vote. >> pelley: well, marco rubio is supposed to be the face of the new republican party, hispanic and young. what happened? >> he was selling the wrong product, that youth, that outreach expansion to new voters and that optimism, it was a year when voters wanted a champion for their anger, and also his greatest legislative achievement, pushing a comprehensive immigration reform bill, that's part of what had stirred up that voter anger in the first place. >> pelley: john dickerson, we'll be watching you sunday on "face the nation." john, thanks. today north korea sentenced a university of virginia student

what amounts to a college prank. otto warmbier was arrested in january for stealing a propaganda banner while visiting with a tour group. the sentence came one day after president obama approved new sanctions against north korea for its recent missile launch and nuclear test. today the nation's second busiest subway system was shut down so problems could be inspected in its electrical system. the d.c. metro serves about 700,000 riders a day, and jeff pegues is following this. >> reporter: emergency inspections had been under way since early this morning. in all 91 stations have been closed as nearly two dozen teams fanned out along more than 100 miles of track looking for damage to third-rail power cables that could lead to smoke and fire. metro general manager paul wiedefeld. >> since we began at midnight,

areas where damaged jumper cables and connector booths exist. >> reporter: on monday a cable fire led to major delays during the morning commute. >> please do not open your doors. >> reporter: it was similar to a serious incident last year that killed a woman and injured dozens. the safety concerns are not new for the 40-year-old metro system. casey dinges, with the american society of civil engineers, says the real issue is funding. >> this fundamental problem we're having here is a lack of investment. but like most of our infrastructure in this country, we tend to take it for granted until it suddenly is not there. >> reporter: metro officials say the tracks will be inspected overnight and they expect the system to be back up and running again by 5:00 a.m. but, scott, commuters are being warned to expect delays. >> pelley: thanks, jeff. change may be coming at arlington national cemetery.

and opiate considered more powerful than morphine. court documents say allen removed the syringes and replaced them with similar ones containing an undisclosed substance. because hospital officials don't know what allen may have done with the replacement syringes, 3,000 former patients are being tested for possible exposure to h.i.v. and hepatitis. attorneys say at least two people have tested positive for hepatitis b. holland hoskins represents some of the patients. >> these are patients that had surgery at swedish medical center during the time period that rocky allen was a surgical tech. they were tested by labcorp and they have tested positive for blood-borne pathogens. >> reporter: 1500 more patients are being tested in hospitals in the seattle area where allen also worked. evan banker is representing allen's potential victims. >> it looks like he was lying about his resume, where he had been. we know he had been fired for the same thing at other facilities. >> reporter: allen has now been fired from at least three

states, including scripps green in la jolla, california. don stazziano is a spokesperson for the hospital. >> he was witnessed by a colleague attempting to divert medication, switching out a syringe of fentanyl for saline. >> reporter: according to his termination letter, allen admitted swapping syringes and planned to inject the drug. rocky allen also served in afghanistan and was court-martialed by the navy in 2011 for stealing the very same drug. the records of that would have been available to any of these hospitals before they hired him, but, scott, they either did not do a for row enough background check or they ignored it. >> pelley: ben tracy in the l.a. newsroom. ben, thank you. and we'll be right back. to increase circulation and accelerate healing. let's review: heat, plus relief, plus healing, equals thermacare.
