In that case, Democrats would be able to draw questions about the president’s behavior out for months, if not longer, keeping a cloud over Mr. Trump as he runs for re-election. Several House committees have already opened broad investigations into Russian election interference, obstruction of justice and abuse of power. Those inquiries can easily funnel in Mr. Mueller’s findings, and serve as a release valve on calls for Mr. Trump’s removal.
Still, Ms. Pelosi and her allies also run risks in not moving toward impeachment. Voices on the Democrats’ left flank appear to have been emboldened by Mr. Mueller’s report, and will remind party leaders that letting Mr. Trump entirely off the hook for behavior they believe threatens the separation of powers sets a dangerous precedent for the country.
Representative Maxine Waters, Democrat of California and the leader of the Financial Services Committee, broke with party leaders on Thursday, saying Congress would be abdicating its responsibility if it does not attempt to remove Mr. Trump.
“At this point, Congress’s failure to impeach is complacency in the face of the erosion of our democracy and constitutional norms,” Ms. Waters said. “Congress’s failure to impeach would set a dangerous precedent and imperil the nation as it would vest too much power in the executive branch and embolden future officeholders to further debase the U.S. presidency, if that’s even possible.”
Other Democrats did their best to avoid any judgments on impeachment on Thursday and instead focused their attention on the actions of Attorney General William P. Barr and an immediate fight over access to Mr. Mueller’s full findings. At least one chairman, whose committee would lead any impeachment proceedings, pointedly refused to say whether he viewed the actions laid out by Mr. Mueller as worthy of opening such an inquiry, though he did not foreclose the possibility.
“It is too early to talk about that,” Representative Jerrold Nadler, Democrat of New York and the chairman of the House Judiciary Committee, told reporters. “We will have to go follow the evidence where it leads. And I don’t know exactly where it will lead.”
