Obama-era Attorney General Eric Holder said Thursday he believes that President Donald Trump committed impeachable offenses.

“There are grounds for impeachment” based on special counsel Robert Mueller’s report, Holder told NBC News in an exclusive interview. “There’s no question that obstruction of justice does exist in the findings that Bob Mueller reported, and in painstaking detail. And that in and of itself would be the basis for impeachment.”

Holder fell shy, however, of calling for the House to begin official proceedings, saying that lawmakers should first hear from Mueller, gather evidence, and see the unredacted report before making a “reasoned decision” on whether to pursue impeachment.
