Trump concerned about being impeached: Report

US President Donald Trump sees his impeachment as a "real possibility" over finance violations during the 2016 campaign, according to a media report.

Impeachment talks have ratcheted up in recent days following a blockbuster filing from prosecutors in the Southern District of New York in which they directly alleged for the first time that Trump's former attorney Michael Cohen was being directed by the president when he broke the law during the 2016 presidential campaign, CNN said.

Trump has expressed concern that he could be impeached when Democrats take over the House, CNN quoted a source close to the president as saying.

Trump is facing off against a series of accusations put together by a team of investigators.

Special counsel Robert Mueller has launched an 18-month investigation into the legitimacy of Donald Trump's 2016 election win.

A source close to the White House told CNN that aides inside the West Wing believe "the only issue that may stick" in the impeachment process is the campaign finance violations tied to former Cohen's payouts to Trump's alleged mistresses, according to the report.

Prosecutors said Trump's lawyer clearly sought to influence the outcome of the 2016 election from the sidelines through illicit payments.

Under US federal law, any payments made for the "purpose of influencing" an election must be reported in campaign finance disclosures.

Prosecutors said Cohen took great steps to hide the payments, creating shell companies, using fake invoices and sending them in small amounts so they wouldn't arouse suspicion.

He arranged for a USD 130,000 payment to adult film star Daniels, which prosecutors concluded violated campaign finance law prohibitions against donations of more than USD 2,700 in a general election.

Trump has denied all wrongdoing and compared the investigations to a witch hunt.

Democrats are suggesting Trump committed an impeachable offense and could be sent to prison when his term in the White House is over.

The incoming chairman of the House Judiciary Committee, Jerry Nadler, said Sunday the allegations, if proven, would constitute "impeachable offenses."
