Cohen’s family, including his wife, children, and in-laws, encouraged him to postpone the appearance after calls by Trump and his lawyer Rudy Giuliani to investigate Cohen’s father-in-law, according to Cohen’s lawyer and spokesman Lanny Davis.

“The president has terrorized someone who wanted to tell the truth before Congress,” Davis said.

Cohen was scheduled to testify before the House Oversight Committee in a public hearing on Feb. 7.

Trump, who has called Cohen a liar and “rat,” said in a tweet on Jan. 18 that Cohen is “Lying to reduce his jail time! Watch father-in-law!”

In a Fox News interview last month, Trump said Cohen’s father-in-law “is a very rich guy, I hear.” Referring to Cohen, the president asked, “Did he make a deal to keep his father-in-law out? Did he make a deal to keep his wife, who supposedly, maybe I’m wrong, but you can check it, did he make keep — make a deal to keep his wife out of trouble?”

Cohen has pleaded guilty to nine felonies and is due to turn himself in on March 6 to begin serving a three-year prison sentence.

He has said Trump directed him to break campaign finance laws by paying hush-money payoffs to two women and that he lied to Congress to hide that negotiations to build a Trump tower in Moscow continued well into the 2016 presidential campaign.

While the House committee would have to steer clear of issues potentially still under investigation by Special Counsel Robert Mueller in an open hearing, leaders of the Senate Intelligence Committee have said they want to hear from Cohen separately in a closed session.

Cohen friend Donny Deutsch, an advertising executive, said that Cohen has been increasingly worried that Trump would retaliate against him by further attacking his family if he testified.

“He was panicked. He was like ‘he’s going after my father-in-law. Are my children next?’” Deutsch said on MSNBC on Jan. 18. Deutsch said Cohen told him, “you have no idea what this man is capable of.”
