after spending nearly two years a the waiting list, mr. cheney received the transplant yesterday. nbc's mike vicara starts us off tonight with the latest at the hospital. >> reporter: dick cheney remains here at the hospital after undergoing a heart transplant surgery early yesterday. we learned this after the fact from a statement from t family. it came as a surprise in that sense, but in another sense, not much of a surprise at all. the vice president has a history of no fewer than five heart attacks, the most recent one about two years ago. he was at george washington university hospital on that occasion and shortly after that, he was outfitted with what's called a left ventricular device. that's for people with end stage heart disease. he was put on a wait list for a heart transplant. just this past december, he reached the top of that list and yesterday he had the surgery. as far as we know, although we have not heard anything from the

doctors or the cheney family since that statement last night where they thanked the now anonymous donor, they thanked the hospital staff and outlined the fact the vice president had been on that list for some 20 months, we assume he's still here in the hospital recovering from the transplant surgery. no word on how long he will be here or his current condition. chris? >> mike vicara, thank you. as mike mentioned, mr. cheney has a lost history of heart problems prior to his most recent in 2010. his first heart attack came in 1978 when he was only 37 years old. he had a second attack six years later followed by emergency q d quadruple bypass in 1988. cheney suffered two more attacks, one in 2000 during the florida recount just before he and former president bush took office. in churches across the country today, congregations wore hoodies, a show of support

stain on the back of his shirt. he claims martin struck him and he went down. >> reporter: his friends are also come to go his defense. >> through his family members, i learned that right after the shooting, he couldn't stop crying. >> reporter: tears shared by thousands now, most part of a growing chorus calling for answers and action. jay gray, nbc news. breaking news in the district. a man is in the hospital tonight after being stabbed in the u street area. d.c. police say officers found the man near 14th and t streets northwest just after 4:00. they have a suspect in custody. he is charged with assault with intent to kill. no word on the victim's condition. well, crowds are gathering outside the u.s. supreme court at this hour on the eve of the historic showdown over president obama's health care reform law. starting tomorrow, the high court will hear three days of arguments from both sides. brian moore reports.

and millions of americans who are in the same boat. >> this is not about health care, it's not even about access to health care, it's related to religious freedoms and religious rights in america. >> reporter: at the supreme court, waiting for history. brian moore, nbc news, washington. and the race for the white house, rick santorum says the battle for the gop nomination is far from over. santorum solidly won yesterday's primary contest in louisiana with double-digit margins. following his victory, he pro claimed himself the true conservative candidate. mitt romney, however, fistill leads with the overall delegate account. he has doubled santorum. they have d.c., maryland and wisconsin a week from tuesday. still ahead tonight, how much money the u.s. government is now paying the victims of a soldier's shooting rampage in afghanistan? we'll hear about the possibility
