U-S President having an active morning on Twitter

President Donald Trump is accusing former President Barack Obama of having Trump's telephones ``wire tapped'' during last year's election, but Trump isn't offering any evidence or saying what prompted the allegation.

Trump says in a series of tweets that he ``just found out that Obama had my 'wires tapped' in Trump Tower.''

There's no immediate White House comment, and an Obama spokesman didn't immediately respond to a request for comment.

Trump's tweets could be in response to Democrat's outcry following revelations that Attorney General Jeff Sessions _ in his confirmation hearings _ didn't disclose his contacts with Russia's

American ambassador during the campaign. Sessions _ a senator at that time _ was Trump's earliest Senate supporter.

U.S. intelligence agencies have concluded Russia influenced the election to help Trump win.
