James Comey 'asked the Justice Department to shoot down President's claim that Obama ordered a wire tap at Trump Tower

Kellyanne Conway has challenged FBI director James Comey to reveal what he knows about President Trump's explosive allegations that Barack Obama ordered the wiretapping of Trump Tower prior to the election. Comey reportedly took the extraordinary step of asking the Justice Department to publicly refute the claims about Obama that the president tweeted out early on Saturday. Trump, who returned to Washington on Sunday from Mar- A-Lago, has not publicly commented on the allegations since he accused Obama of spying on him before the election. White House press secretary Sean Spicer said on Sunday Trump was calling on Congress to investigate. Obama's director of national intelligence James Clapper told NBC's Chuck Todd he 'absolutely denies' Trump's claim of wiretapping. A spokesman for the former president released a statement Saturday afternoon refuting Trump's claims.
