Several other depositions of administration officials have been delayed until next week because of events honoring Representative Elijah E. Cummings, the Maryland Democrat who died last week, Democratic officials said.
To keep Republicans on the defensive in the interim, Ms. Pelosi held a House vote last week on Mr. Trump’s decision to pull back American troops from Syria — which was widely panned by lawmakers in both parties — and will force a vote this week on measures to combat foreign election interference.
On Monday, Ms Pelosi offered the latest bit of what has become a daily, sometimes hourly, stream of information to shape the Democrats’ argument, circulating a fact sheet for reporters entitled “Truth Exposed: The Shakedown, the Pressure Campaign and the Cover-up” to sum up what has been learned about the Ukraine affair so far, along with a 90-second video laying out the case for impeaching Mr. Trump.
Ms. Pelosi’s aides have advised lawmakers to avoid talking at length about bit players or subplots in the drama they are unspooling, emphasizing the need to return again and again to Mr. Trump’s own words from a July phone call with President Volodymyr Zelensky of Ukraine. “Do Us a Favor,” a quote from a reconstructed transcript of that call, was the title of their video.
Democratic leaders have pushed lawmakers with backgrounds in law enforcement or national security to make television appearances to discuss the inquiry, including Representative Elissa Slotkin of Michigan, a former C.I.A. analyst; Representative Val Demings of Florida, a former police chief; and Representative Tom Malinowski of New Jersey, a former State Department official.
“If we get mired in esoteric process concerns, we will lose the ability to tell a powerful story to the American people about the abuse of power that is connected to the Trump-Ukraine scandal,” Mr. Jeffries said.
Some Republicans, already uneasy about the allegations at the heart of the Ukraine inquiry, have grown increasingly uncomfortable with Mr. Trump’s behavior, and unwilling to defend him on a range of topics, including the Syria decision and his plan — abruptly abandoned in the face of a bipartisan outcry — to hold the Group of 7 summit of world leaders at one of his resorts in Florida.
