And invasive patdowns. Reports of new, rigorous patdowns at Airport Security checkpoints. If you want to fly, get ready to get more up close and personal with the tsa. And good evening. Thanks for joining us on a very busy saturday. Im tom llamas. We begin tonight with that breaking news, President Trumps striking allegations against former president barack obama. President trump in a twitter tirade accusing the former president of spying on him at trump tower by wiretapping phones but offering no evidence, or even what prompted those allegations. A spokesman for president obama firing back, saying, neither the former president nor the Obama White House ordered or interfered with any such surveillance. This, following a dramatic and heated exchange, you see it there, inside the oval office with key aides abcs chief investigative correspondent brian ross leading us off tonight. Reporter it was just before sunrise in palm beach, when the president of the United States took to twitter to make one of his most stunning accusations ever. Terrible. Just found out that obama had my wires tapped in trump tower just before the victory. Nothing found. Followed by four more president ial outbursts taking on president obama and misspelling tap. How low has president obama gone to tapp my phones during the very sacred election process. This is nixon watergate. Bad or sick guy today, a senator from the president s own party, along with u. S. Intelligence officials, called it a troubling development. I am very worried. Im very worried that our president is suggesting that the former president has done something illegal. Reporter it would be a crime to reveal such a secret fbi wiretap on trump tower and no u. S. Official contacted by abc news would confirm the allegation. Its an extremely serious offense. Anyone who would reveal the existence of a wiretap would violate federal law. Reporter because the president cited no proof, it is not clear tonight whether he based his allegations on a top secret white house briefing. Or whether it came from reading an article on the conservative breitbart website, posted friday, that detailed speculation from a conspiracyloving talk show host mark levin. How many of trumps people were eavesdropped on . How many had their conversations intercepted, recorded, transcribed . Because this, ladies and gentlemen, is the big scandal. Reporter a spokesperson for president obama quickly called the allegations false. And one of obamas former National Security aides, ben rhodes, responded to trump no president can order a wiretap. Those restrictions were put in place to protect citizens from people like you. The president s twitter rage today did serve to keep the focus on russia, and contacts between the Russian Ambassador and at least five top trump advisers. And it comes a day after a democratic member of the Senate IntelligenceCommittee Told abc news that key wiretaps are part of the investigation although he said he has not read them. There are transcripts that provide very helpful, very critical insights into whether or not russian intelligence and senior russian political leaders including vladimir putin, were cooperating or colluding with the Trump Campaign at the highest levels to influence the outcome of our election. And chief investigative correspondent brian ross joins us live now. From what we know, theres a kernel of truth to what the president was saying, but he may have raised some serious legal issues. Thats right. The fbi is investigating whether there was possible collusion between russian spies and the trum and in cases like that, wiretaps can be used. But if anyone other than the president reveals the existence of a wiretap, that breaks the law. Legal experts tell us the president has the power to declassify anything he wants. A story still developing, all right, brian, thanks so much. Now to that escalating Political Drama unfolding inside 1600 pennsylvania avenue. Senior white house sources tell abc news that the president went quote, ballistic with a meeting with top staff over attorney Jeff Sessions recusal.

Reporter hours earlier, trump had expressed his full confidence in the ag. Should sessions recuse himself from investigations into your campaign and russia . I dont think so.

We should have had a good weekend. But once again back to russia. Thats how one senior official summed it up. Bannon and priebus were both scheduled to accompany the president to florida. But sources say after this meeting, those plans abruptly changed. At 10 45, the president held hands with his grandchildren as he crossed the south lawn to the helicopter. His daughter ivanka and soninlaw Jared Kushner joined him. But as marine one made the tenminute flight to rendezvous with air force one, staffers called ahead, removing bannon and priebus from the manifest. These two key advisers sidelined, at least for this trip. And david joins us live now. David, what a difference a day makes.
