As the facts around Mr. Trump’s alleged pressure campaign came into clearer focus, though, significant questions went unanswered about the scope and speed of Democrats’ inquiry, with lawmakers from the party’s progressive and moderate wings at odds over how to handle accusations of presidential wrongdoing.
For now at least, Democrats do not intend to limit their inquiry to the Ukraine episode. They are planning to consider other matters they have been investigating as possible impeachable offenses, including the findings of the special counsel, Robert S. Mueller III, who investigated Russia’s interference in the 2016 elections and Mr. Trump’s attempts to derail that inquiry. Each could still form the substance of separate articles of impeachment for consideration by the House.
But during a meeting with members of her leadership team, the speaker initiated a discussion about whether Democrats should limit their case strictly to the Ukraine matter and attempts by Mr. Trump and his administration to keep it from Congress, people familiar with the conversation said. An aide to Ms. Pelosi cautioned that no final decisions had been made.
Proponents of limiting the impeachment inquiry argue that the Ukraine case makes for a fresher, simpler case to make to voters, but also that it could create space for national security-minded Republicans to cross party lines.
Representative Mikie Sherrill, a freshman Democrat who represents a swing district in New Jersey, said her party had not made its case to voters that Mr. Trump obstructed justice in the Russia investigation, and would be better served to confine the impeachment inquiry to the president’s dealings with Ukraine.
