President Trump's accusation that former President Obama tapped his telephones during the 2016 presidential race and Trump's call Sunday for Capitol Hill investigations into the matter received qualified support from the GOP leaders of Congress' top Intelligence panels.
In one of the tweets, Mr Trump said the alleged wiretapping took place in his Trump Tower skyscraper in NY. "Nothing found. This is McCarthyism!" he tweeted. Presidents do not have the authority to order such wiretaps and would not even be aware of them as a routine matter.
News reached out to former Obama administration officials and the White House for comment and clarification but had not heard back.
Sen. Susan Collins says it would be helpful if President Trump turned over any evidence he might have of alleged wiretapping by the Obama administration to the Senate Select Committee on Intelligence in its investigation of Russian efforts to influence the presidential campaign.
Obama spokesman Kevin Lewis quickly dismissed Trump's claims as "unequivocally false". The FBI has investigated Trump associates' ties to Russian officials.

While questions continue over the Trump campaign's contact with Russian Federation, today President Trump dropped an explosive allegation. "Any suggestion otherwise is false", he said.
Obtaining wiretaps would require officials at the Justice Department to seek permission from the Foreign Intelligence Surveillance Court, which is shrouded in secrecy.
The White House is said to be working on its own response to the president's early morning tweets. "Those restrictions were put in place to protect citizens from people like you", he said in his Twitter post.
