This is pretty serious. Not sure he can bluster his way out of this, but time will tell.
"Former Director of National Intelligence James Clapper said there was no wiretap activity directed against President Donald Trump or his campaign by the Obama administration, as Trump has suggested in calling for a Congressional investigation, and no court order allowing it.
“I can deny it,” Clapper, weeks removed from serving in the federal government, said Sunday on NBC’s “Meet the Press” on Sunday when asked whether he could confirm or deny a court order allowing for eavesdropping at Trump Tower in New York.
Clapper’s comments contradicted claims by Trump that President Barack Obama had the Republican’s “wires tapped in Trump Tower just before” the 2016 presidential election. Trump relied on reports in conservative media, including Breitbart News, a person familiar with the situation told Bloomberg."
