"He's tweeted at me probably 50 times," Comey told Stephen Colbert during the late-night show.

"I've been gone for a year, I'm like the breakup he can't get over. He wakes up in the morning ... I'm out there living my best life, he wakes up in the morning and tweets at me."

Trump and his administration in recent days have gone on the attack against Comey as the former FBI director continues a media tour promoting his book "A Higher Loyalty: Truth, Lies, and Leadership."

The president has targeted Comey several times in tweets and White House press secretary Sarah Huckabee Sanders said last week that Trump's firing of Comey will be "one of the president’s greatest achievements."

Over the weekend, Trump referred to Comey, who he fired last year, as a "slimeball" and said he would go down as the worst FBI director in history.

Trump also denied ever asking for Comey's loyalty and questioned why "the big questions in Comey's badly reviewed book aren't answered."

Comey has done a number of interviews, his first since being fired by Trump, in recent days to promote the book. 

During an interview on ABC that aired Sunday night, Comey said there's "certainly some evidence" Trump obstructed justice when he asked about the investigation into former national security adviser Michael Flynn.

Comey also said during the interview that aired Sunday he thinks it's possible Trump is compromised by Russia.
