House Intelligence Committee Chairman Rep. Devin Nunes and ranking member Rep. Adam Schiff have told the White House to offer by Monday any evidence showing Trump Tower was wiretapped.
Trump has kept his distance from the press since last weekend and has been all but invisible, when he accused former President Barack Obama of wiretapping Trump Tower before the November election.
Trump did not provide any evidence of the claim, and a spokesperson for Obama denied that he or any White House official called for the surveillance.
The White House has asked that an investigation of the alleged wiretaps be part of the probe into Russia’s interference in the presidential election.
Nunes has said that the intelligence panel would investigate potential surveillance of political parties as part of its Russia inquiry.
