Speaker Nancy Pelosi and three Democratic chairs of committees investigating Donald Trump’s alleged misconduct on Wednesday cracked the door to eventually launching impeachment proceedings against the president, using rhetoric that sounded like that is where their investigations are headed.

“When we go down this path, we want it to be unifying for our country, not divided. And that’s why we want it to be the strongest possible case,” Pelosi told reporters Wednesday evening after former special counsel Robert S. Mueller III testified before the House Judiciary and Intelligence committees about his report on Russian interference in the 2016 elections.

“President Lincoln said public sentiment is everything,” the California Democrat continued. “Well, in order for the public to have the sentiment, the public has to know. So hopefully, we’ll be messengers of the truth to the public. We think today was really a milestone in making that sentiment.”

Pelosi said the two hearings with Mueller demonstrated that obstruction of justice allegations against Trump would be indictable offenses if committed by anyone but a sitting president. She noted that Trump could still be indicted for the offenses after he leaves office, as Mueller stated in his testimony Wednesday.

House Democrats plan to go a step further than Mueller did in his report by digging into Trump’s finances, Pelosi said.
