The Washington Post reported March 5th,
A day after President Trump alleged — without offering any evidence — that President Barack Obama had ordered the wiretapping of the Republican’s campaign headquarters, the White House said it won’t comment further until congressional oversight committees investigate the matter.
In a statement, White House press secretary Sean Spicer cited unknown “reports” of “potentially politically motivated investigations” during the 2016 campaign, calling them “troubling.”
“Reports concerning potentially politically motivated investigations immediately ahead of the 2016 election are very troubling,” Spicer said. “President Donald J. Trump is requesting that as part of their investigation into Russian activity, the congressional intelligence committees exercise their oversight authority to determine whether executive branch investigative powers were abused in 2016.”
… Early Saturday, Trump — apparently in response to reports by a conservative radio host and on the conservative website Breitbart — accused Obama of wiretapping Trump Tower and engaging in a “Nixon/Watergate” effort to undermine his presidency.
This is the article that apparently inspired president Trump: Mark Levin to Congress: Investigate Obama’s ‘Silent Coup’ vs. Trump, Joel B. Pollack, Breitbart. Lyndsey Graham commented on the situation at town meeting:
I’d be very worried if in fact the Obama administration was able to obtain a warrant lawfully about Trump campaign activity with foreign governments. It’s my job as United States senator to get to the bottom of this.
It is time to be very worried. Louise Mensch reported in November of 2016,
Two separate sources with links to the counter-intelligence community have confirmed to Heat Street that the FBI sought, and was granted, a FISA court warrant in October, giving counter-intelligence permission to examine the activities of ‘U.S. persons’ in Donald Trump’s campaign with ties to Russia.
The reason Graham says he would be worried if a FISA court granted a warrant about Trump campaign activity is that FISA courts do not grant a warrant without just cause. Trump’s comments have provided additional evidence that confirms Mensch’s reporting.
The Director of the FBI has asked the Justice Department to refute Trump’s claim.
