If in fact Trump Tower was wiretapped during the 2016 presidential campaign, as President Trump claimed in several tweets Saturday morning, he can do much more than say so on twitter: Presidents have the power to declassify anything at any time, so Trump could immediately make public any government records of such surveillance.
What Trump is saying seems to be a garbled version of previous reporting by the BBC, among other news outlets.
According to a report in the BBC, citing unnamed sources, a joint government task force was formed in spring of 2016 to look into an intelligence report from a foreign government that Russian money was somehow coming into the U.S. presidential race. In June the Department of Justice, part of the task force, asked the Foreign Intelligence Surveillance Act court for a warrant to intercept electronic communications by two Russian banks.
However, the BBC’s report says, the FISA court turned the application down.. The Justice Department then asked again in July with a more narrowly drawn request, which was again turned down. Justice then made a third request for a warrant on October 15, which was granted.
