1. President Trump’s longtime lawyer, Michael Cohen, secretly recorded Mr. Trump before the 2016 election discussing payments to a former Playboy model who claimed she had an affair with him.

The Justice Department is investigating Mr. Cohen’s involvement in paying women — including the model, Karen McDougal — to tamp down embarrassing news stories about Mr. Trump ahead of the election.

Prosecutors want to know whether the payment violated federal campaign finance laws.

The Trump campaign previously denied knowledge of any payments to Ms. McDougal. But Rudolph Giuliani, Mr. Trump’s personal lawyer, called the tape “powerful exculpatory evidence.”
