Trump ramps up his allegations against Obama

President Donald Trump called Sunday for a congressional investigation into whether his predecessor abused his executive powers during the election campaign last year by having Trump Tower wiretapped in connection with an investigation of Russian interference. "Reports concerning potentially politically motivated investigations immediately ahead of the 2016 election are very troubling," White House spokesman Sean Spicer said in a statement Sunday. The congressional probe should be part of the investigation into Russian activity, the White House said.

In reference to Obama, Trump tweeted earlier. "Who was it that secretly said to Russian President, 'Tell Vladimir that after the election I'll have more flexibility?'" 

DEBKAfile’s intelligence sources: The president and Spicer hint at evidence that Obama had the campaign illegally monitored to uncover alleged ties with Russia and so cause Trump to lose the election.
