Former President Donald Trump's daughter, Ivanka Trump, reacted to the indictment on Instagram Friday, writing, "I love my father, and I love my country. Today, I am pained for both."

She added, "I appreciate the voices across the political spectrum expressing support and concern."

Sources familiar with the matter told ABC News the Manhattan district attorney’s office is also investigating a $150,000 payment to Playboy model Karen McDougal, who, like Stormy Daniels, claimed to have had an affair with Donald Trump.

The former president has denied having an affair with either woman and has called the investigation a witch hunt.

McDougal was paid for the rights to her story in August 2016 by American Media, publisher of the National Enquirer, which did not publish it, a practice known as catch and kill.

Michael Cohen, Trump’s former lawyer and fixer, has said he recorded Trump discussing reimbursement to American Media for the payment to McDougal, but the payment was never made.

Trump has not responded to ABC News' request for comment but in a 2018 interview with Fox News, he claimed he wasn't aware of any payment made to AMI to facilitate the alleged hush agreement.

Judge Juan Merchan has signed this order allowing the Manhattan district attorney's office to publicly acknowledge the indictment.

Manhattan District Attorney Alvin Bragg on Friday again resisted the House GOP investigation of his office’s prosecution of Trump.

Bragg’s legal counsel called the inquiry “illegitimate incursion” into a legitimate investigation.

The House Republicans -- Reps. Jim Jordan, James Comer and Bryan Steil -- have said they want to find evidence of federal funds used to investigate Trump. But Bragg’s office said they were merely doing Trump’s bidding.

“Finally, as you are no doubt aware, former President Trump has directed harsh invective against District Attorney Bragg and threatened on social media that his arrest or indictment in New York may unleash 'death & destruction.' As Committee Chairmen, you could use the stature of your office to denounce these attacks and urge respect for the fairness of our justice system and for the work of the impartial grand jury," counsel Leslie Dubeck wrote in a letter to the lawmakers.

"Instead, you and many of your colleagues have chosen to collaborate with Mr. Trump’s efforts to vilify and denigrate the integrity of elected state prosecutors and trial judges and made unfounded allegations that the Office’s investigation, conducted via an independent grand jury of average citizens serving New York State, is politically motivated.”

While 45% of Americans believe former President Donald Trump should face charges in an investigation by the Manhattan District Attorney's Office, 32% say he shouldn't have been indicted, according to a new ABC News/Ipsos poll.

Another 23% of American say they don't know whether the nation's 45th president should face charges.

While the charges have not been announced, a Manhattan grand jury that indicted Trump had been hearing evidence in a $130,000 hush money payment Trump allegedly made to adult film actress Stormy Daniels, who claims they had an affair. Trump has denied the allegations.

The poll showed a split in opinions along party lines. While 88% of Democrats said Trump should face charges, 62%, of Republicans said the former president should not have been charged while 16% said he should be charged, and the remainder was uncertain.

About 47% of Americans polled say the charges are politically motivated, echoing the sentiment from top GOP figures. About 79% of Republicans hold that view.
