Aides to House Judiciary Committee Chairman Jerrold Nadler (D-N.Y.) say the congressman has privately voiced support for impeachment proceedings against President Trump, The Washington Post reported Sunday. 

Nadler has not publicly come forward with supporting impeachment inquiries into Trump, despite mounting pressure from within his own party. 

On “Fox News Sunday,” Nadler said he believes former special counsel Robert Mueller’s report “presents very substantial evidence that the president is guilty of high crimes and misdemeanors.”{mosads} 

“The administration must be held accountable,” he said.

Nadler, however, stopped short of publicly calling for an impeachment inquiry.

His comments come days ahead of Mueller’s testimony before the House Judiciary Committee. 

There are currently 87 House Democrats backing an impeachment inquiry, according to The Hill’s whip list.

The Hill has reached out to Nadler’s office for comment. 

Speaker Nancy Pelosi (D-Calif.) has said House Democrats will not proceed with an impeachment inquiry at this time. 

Mueller will testify Wednesday in a three-hour hearing before the House Judiciary Committee and two-hour hearing before the House Intelligence Committee regarding allegations of Trump’s obstruction of justice outlined in his more than 400-page report.
