American Media Inc. Chief Executive Officer David Pecker, embroiled in a scandal involving alleged payments to women who had affairs with President Donald Trump, resigned from the board of Postmedia.

Postmedia Network Canada Corp. (PNCa.TO) said Tuesday that Pecker informed the company of his decision to step down. He has served as a director since October 2016.

“David noted that it is important for him to focus his efforts on ensuring that his businesses are best positioned for continued growth,” Peter Sharpe, lead director at Postmedia, said in a statement.

Last week, Trump’s personal lawyer, Michael D. Cohen, pleaded guilty to criminal charges and said American Media knew about or played a role in payments before the 2016 election to two women who had had affairs with Trump more than a decade ago. The payments were directed by Trump and amounted to illegal campaign contributions, Cohen alleged.

Since Cohen spoke earlier this week, it has emerged that federal authorities have granted immunity to two key witnesses. Allen Weisselberg, the longtime chief financial officer of the Trump Organization, is cooperating, the Wall Street Journal reported. So is Pecker, whose American Media owns the National Enquirer and allegedly made “catch and kill” deals that helped keep illicit affairs out of public view, Vanity Fair first reported.
