Donald Trump, former US President, has been invited to testify before a New York grand jury, his attorney Joseph Tacopina said on Thursday. The Republican is being investigated for the alleged hush money payments that were made on his behalf during the 2016 campaign. This could be the first criminal case brought against a former president.

Manhattan prosecutors might press criminal charges against Trump relating to his alleged role in hush money payments to adult film star Stormy Daniels, the New York Times reported on Thursday, citing four unnamed sources.

“He has a chance to appear before the grand jury as all people subject to an investigation do,” Trump attorney Susan Necheles told Reuters.

Donald Trump on Truth Social said that this is a political witch hunt.  “I did absolutely nothing wrong, I never had an affair with Stormy Daniels, nor would I have wanted to have an affair with Stormy Daniels. This is a political Witch-Hunt, trying to take down the leading candidate, by far, in the Republican Party.”

Daniels had said that she had a sexual liaison with Trump. The 43-year-old added that she received $130,000 before the 2016 presidential election in exchange for not talking about it.

The former President’s personal lawyer Michael Cohen was sentenced to three years for orchestrating hush payments to Daniels and former Playboy model Karen McDougal, who said that she had a months-long affair with Trump before he took office.

McDougal, in an interview on CNN, admitted that she knew he was married while they were having an alleged affair.

“What can you say except I’m sorry?” she told CNN’s Anderson Cooper, apologizing to Melania Trump. “I’m sorry. I wouldn’t want it done to me.”

“After we had been intimate, he tried to pay me, and I actually didn’t know how to take that,” McDougal said. “I’ve never been offered money like that. I looked at him and said, ‘I’m not that type of girl.”
