if the justice department has any proof of wiretapping at trump tower - a congressional committee wants that evidence turned over - by tomorrow. the deadline looms as pressure mounts on president trump to drop his wiretapping claim against president obama - or prove it. here's errol barnett. >> the president has one of two choices, either retract or to provide the information that the american people deserve. >> republican senator john mccain said today that he has no reason to believe president trump's claim of being wiretapped. >> i hope we get to the bottom of all these matters. >> republican senate intelligence committee member, tom cotton said he has seen no supporting evidence, neither has the ranking democrat on the house intelligence committee >> either the president quite deliberately for some reason made up this charge or perhaps more disturbing the president really believes this. >> last weekend, president trump tweeted that president obama ordered surveillance of trump tower during the election. he offered no evidence or further explanation.

>> no i said i'm thought aware and i'm not aware. >> press secretary sean spicer struggled to clarify if the surveillance occurred because mister trump was already part of investigations into russia. that's why we want the house and senate to do what the president has asked of them to look into this. >> house members are asking the department of justice to turn over any evidence of wire tapping by monday. president obama's director of national intelligence has disputed the president's claim. >> there was no such wiretap activity mounted against the president elect at this time. >> president trump has asked congress to investigate his wiretapping accusation against president obama, while congress

is still waiting for any supporting evidence from the white house. meanwhile, fbi director james comey is scheduled to testify before the house committee on this matter one week from tomorrow, elaine.. erroll barnett thanks. tomorrow, the "congressional budget office" - a non-partisan agency of economists - is expected to release its report on the "american health care act" - the republican plan to repeal and replace obamacare. the report will outline the estimated cost and impact of the bill. the re-ignited health care debate was a hot topic on the sunday morning programs. house speaker paul ryan weighed in on "face the nation" with john dickerson. >> the one thing i'm certain will happen is c.b.o. will say, "well, gosh. not as many people will get coverage." you know why? because this isn't a government mandate. this is not the government makes you buy what we say you should buy and therefore the government thinks you're all going to buy it. so there's no way you can compete with on paper a government mandate with coverage. what we are trying to achieve here is bringing down the cost of care, bringing down the cost of care, bringing down the cost of insurance, thought through government mandates and monopolies but by having more choice and competition. >> quijano: john dickerson is with us now from washington. so john, the congressional budget office's assessment of the plan,

as you know, is expected on monday. now if it predicts that millions will lose coverage what are the arguments that we will likely here from those republicans who backed this bill? >> well, here's why that's such a problem. president trump said more people will be covered than are nik0 currently covered. white house adviser kellyanne conway said everybody who is covered by the affordable care act will be covered. this has been the consistent message from the president. leaving aside the promises the president also made about quality and choice which are quite robust promises. so that's why this is a big hurdle if cbo comes out and makes this judgment. >> quijano: if this legislation fails what is the potential political fallout for the white house as well as congressional republicans? >> well if it fails completely and there is no replacement for the aca -- the president has said that would be a blood bath and paul ryan on the broadcast today affirmed that. so that would be the big disaster. the interim situation would be -- what happens often in legislation -- which is it

fails, and then people cobble together a solution and try to run up the hill one more time. the challenge here is that the republicans are operating within their own space and are not picking up any democrats and not appealing to them. >> quijano: john dickerson in washington, john thank you. the california man who hopped the white house fence, and tried to pay a midnight visit to president trump over the weekend - is due in federal court tomorrow. demarco morgan has the latest. >> family members told reporters.ùjonathan tran was troubled after being laid off from a job at an engineering company. hehad been stressed out, living is in his car, eating junk food. the 26 year old from milpedis, -- milpitas, california, graduated from san jose state university in 2015. in u.s. district court saturday afternoon, tran was charged with entering restricted grounds while carrying a dangerous weapon. according to the criminal complaint, just before midnight
