Former FBI Director James Comey reportedly told associates in March that President Trump was “crazy” for suggesting former President Barack Obama had wiretapped him.

Comey also called the president “outside the realm of normal,” according to a report from The New York Times on Wednesday.

The Times said that, in return, Trump was furious when Comey publicly refused to back his claims that he was wiretapped during the 2016 campaign before the House Intelligence Committee in March.

Comey said during the March 20 hearing that the FBI had “no information” supporting Trump’s allegations.
