A wiretap cannot be directed at a U.S. facility, the official said, without finding probable cause that the phone lines or Internet addresses were being used by agents of a foreign power — or by someone spying for or acting on behalf of a foreign government. “You can’t just go around and tap buildings,” the official said.Rep. Adam Schiff (Calif.), the ranking Democrat on the House Permanent Select Committee on Intelligence, issued a statement chastising Trump for leveling a “spectacularly reckless allegation” against Obama without evidence.Referencing Trump’s description of Obama as a “bad (or sick) guy,” Schiff said, “If there is something bad or sick going on, it is the willingness of the nation’s chief executive to make the most outlandish and destructive claims without providing a scintilla of evidence to support them. “Trump sent the tweets from Palm Beach, Fla., where he is vacationing this weekend at his private Mar-a-Lago estate. It has long been his practice to stir up new controversies to deflect attention from a damaging news cycle, such as the one in recent days about Sessions and Russia.After visiting one of his golf courses on Saturday morning, Trump amended his public schedule to add a late-afternoon meeting with Sessions and Homeland Security Secretary John Kelly at Mar-a-Lago. The president also is planning to have dinner there with both secretaries, as well as chief White House strategist Stephen K. Bannon, Commerce Secretary Wilbur Ross, White House Counsel Don McGahn and White House senior policy adviser Stephen Miller.Trump had departed Washington in a fury on Friday, fuming at a senior staff meeting in the Oval Office that morning about Sessions’ decision to recuse himself. Trump was angry and told his top aides that he disagreed with the attorney general’s decision and that he thought the White House and Justice Department should have done more to counter the suggestion that Sessions needed to step away. The president told staff he wanted to see them fight back against what he saw as a widespread effort to destabilize his presidency, according to senior White House officials who were not authorized to speak publicly.
