House Democratic leaders are grappling with a caucus divided over how to proceed after Mueller found several instances of Trump potentially obstructing justice.

"While our views range from proceeding to investigate the findings of the Mueller report or proceeding directly to impeachment, we all firmly agree that we should proceed down a path of finding the truth. It is also important to know that the facts regarding holding the President accountable can be gained outside of impeachment hearings," Pelosi wrote in a letter to House Democrats.

"As we proceed to uncover the truth and present additional needed reforms to protect our democracy, we must show the American people we are proceeding free from passion or prejudice, strictly on the presentation of fact."

Pelosi emphasized that the caucus will continue with its investigative efforts.

"As to the President’s conduct, we will scrupulously assert Congress’ constitutional duty to honor our oath of office to support and defend the Constitution and our democracy. That includes honoring the Article I responsibility of the legislative branch to conduct oversight over the other branches of government, unified in our search for the truth and in upholding the security of our elections."

House Democrats will convene via conference call at 5 p.m. in their first caucus-wide gathering since holding a retreat in Leesburg, Va., before the Easter break.

Top committee chairmen haven't ruled out the possibility of impeachment while stressing that their investigations will continue.

"I think what we’re going to have to decide as a caucus is what is the best thing for the country. Is the best thing for the country to take up an impeachment proceeding because to do otherwise sends a message that this conduct is somehow compatible with office or is it in the best interest of the country not to take up an impeachment that we know will not be successful in the Senate because the Republican leadership will not do its duty? That’s a very tough question and I think is one we ought not to make overnight," Schiff said.

Republicans have largely echoed President Trump in claiming the Mueller report offers exoneration because it did not find conclusive evidence of the Trump campaign colluding with the Russian government's 2016 election interference efforts. Only a handful of Republicans have expressed concerns about the report's detailing of Trump attempting to undermine the investigation, such as Sen. Mitt Romney Willard (Mitt) Mitt RomneyBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Romney: 'Unthinkable and unacceptable' to not commit to peaceful transition of power The Memo: Trump's strengths complicate election picture MORE (R-Utah), who said he was "sickened."

Pelosi blasted Republicans for siding with Trump. In her past remarks watering down the notion of impeachment, Pelosi has said that any such effort would have to be bipartisan in order to feasibly go forward.

"Whether currently indictable or not, it is clear that the President has, at a minimum, engaged in highly unethical and unscrupulous behavior which does not bring honor to the office he holds. It is also clear that the Congressional Republicans have an unlimited appetite for such low standards. The GOP should be ashamed of what the Mueller report has revealed, instead of giving the President their blessings," Pelosi wrote in the letter.
