He was simply relying on his attorney

As a presidential candidate in August 2015, Donald Trump huddled with a longtime friend, media executive David Pecker, in his cluttered 26th floor Trump Tower office and made a request.

What can you do to help my campaign? he asked, according to people familiar with the meeting.

Mr. Pecker, chief executive of American Media Inc., offered to use his National Enquirer tabloid to buy the silence of women if they tried to publicize alleged sexual encounters with Mr. Trump.

Less than a year later, Mr. Trump asked Mr. Pecker to quash the story of a former Playboy model who said they’d had an affair. Mr. Pecker’s company soon paid $150,000 to the model, Karen McDougal, to keep her from speaking publicly about it. Mr. Trump later thanked Mr. Pecker for the assistance.

The Wall Street Journal found that Mr. Trump was involved in or briefed on nearly every step of the agreements. He directed deals in phone calls and meetings with his self-described fixer, Michael Cohen, and others. The U.S. attorney’s office in Manhattan has gathered evidence of Mr. Trump’s participation in the transactions.

Donald Trump was the third person in the room in August 2015 when his lawyer Michael Cohen and National Enquirer publisher David Pecker discussed ways Pecker could help counter negative stories about Trump's relationships with women, NBC News has confirmed.

As part of a nonprosecution agreement disclosed Wednesday by federal prosecutors, American Media Inc., the Enquirer's parent company, admitted that "Pecker offered to help deal with negative stories about that presidential candidate's relationships with women by, among other things, assisting the campaign in identifying such stories so they could be purchased and their publication avoided."

The "statement of admitted facts" says that AMI admitted making a $150,000 payment "in concert with the campaign," and says that Pecker, Cohen and "at least one other member of the campaign" were in the meeting. According to a person familiar with the matter, the "other member" was Trump.

Daniel Goldman, an NBC News analyst and former assistant U.S. attorney said the agreement doesn't detail what Trump said and did in the meeting. "But if Trump is now in the room, as early as August of 2015 and in combination with the recording where Trump clearly knows what Cohen is talking about with regarding to David Pecker, you now squarely place Trump in the middle of a conspiracy to commit campaign finance fraud."
