Manhattan prosecutors investigating Donald Trump’s role in paying hush money to a porn star also have been examining a $150,000 payment to a former Playboy model who alleged that she had an affair with the former president, according to people familiar with the matter, raising the prospect that Mr. Trump could face charges connected to the silencing of both women.

Manhattan District Attorney Alvin Bragg’s office has been presenting a grand jury with evidence of Mr. Trump’s involvement in a $130,000 payment to porn star Stormy Daniels since January. In those proceedings, the people said, Mr. Bragg’s prosecutors also have questioned grand-jury witnesses extensively about an earlier deal involving Karen McDougal, Playboy Magazine’s Playmate of the Year in 1998, who has said she began a 10-month relationship with Mr. Trump in 2006.

The extent of prosecutors’ interest in Ms. McDougal hasn’t been previously reported.

[Actually, I’ve been raising that possibility ever since David Pecker got called to testify again. The former National Enquirer CEO didn’t have much to do with the Stormy Daniels payoff, but he was central to the McDougal scheme. Here’s the link to my analysis yesterday. FWIW, this case is almost as big a loser, but it’s less reliant on Michael Cohen. — Ed]
