"This is McCarthyism!" Mr. Trump tweeted early in the morning from his Mar-a-Lago retreat in Palm Beach, Florida, as the President offered no evidence to explain why the FBI would have wiretapped his phone.
The Saturday morning Twitter blast came after what several news organizations said was an Oval Office outburst directed by the President at his senior staff on Friday, reportedly angry about the move by Attorney General Jeff Sessions to recuse himself from any probe related to Russia.
On the road in Virginia on Thursday afternoon, the President had told reporters that he saw no need for Sessions to recuse himself; not long after, the Attorney General announced exactly that.
More than 12 hours after Mr. Trump's tweets, there still had been no official comment from the White House; the President spent part of his day at one of his golf courses in Florida, and was having dinner with several of his Cabinet secretaries.
As for Democrats, they used the latest outburst by the President to demand a special counsel probe of any links between Russia and the Trump campaign.
