Twitter missed a Monday deadline to respond to written questions from the Senate Intelligence Committee about Russian online interference in the election, the panel's top Democrat said on Tuesday.

“Facebook and Google met the deadline, and [with] voluminous amounts of information, Twitter did not,” Sen. Mark Warner told Axios. “I’m disappointed in Twitter.”

Why it matters: Warner slammed Twitter in September for what he said was an “inadequate” response to questions from committee staffers investigating Russia’s election disruption campaign.

The details:

  • Lawmakers on the committee posed the written question to the Silicon Valley companies after their top lawyers appeared at a November hearing on the Russia issue.
  • “They need to understand when they bring in their senior executives and testify before Congress, when Congress then has follow-up written questions, we expect them to answer those questions,” Warner said of Twitter. “So if it’s a day or two, fine, but if this is one more attempt for them to kind of punt on their responsibility that will not go down well with the committee.”
  • A Twitter spokeswoman said: "We are continuing to work closely with committee investigators to provide detailed, thorough answers to their questions. As our review is ongoing, we want to ensure we are providing Congress with the most complete, accurate answers possible. We look forward to finalizing our responses soon."

This story has been updated to include Twitter's response.

The clock is ticking for tens of thousands of anxious airline employees, who face mass reductions when the government's current payroll support program expires on Sept. 30.

Where it stands: Airline CEOs met Thursday with White House Chief of Staff Mark Meadows, who said President Trump would support an additional $25 billion from Congress to extend the current aid package through next March.

Four Democratic House committee chairs on Friday asked the Justice Department's inspector general to launch an "emergency investigation" into whether Attorney General Bill Barr and U.S. Attorney John Durham, his appointee, are taking actions that could "improperly influence the upcoming presidential election."

Catch up quick: Last year, Barr tapped Durham to conduct a sweeping investigation into the origins of the FBI's 2016 Russia probe, after he and President Trump claimed that it was unjustified and a "hoax."
