The National Security Agency confirmed to ABC News that Michael Ellis has been named to be the agency’s new general counsel.

Ellis, who is considered to be a Trump loyalist, was pre-selected for the job, but his placement was slow-rolled by NSA Director Paul M. Nakasone.

Acting Defense Secretary Chris Miller demanded the NSA to put him in the career civil service job by 6 p.m. Saturday night, according to a source.

"Mr. Ellis accepted his final job offer yesterday afternoon. NSA is moving forward with his employment," an NSA spokesperson said in a statement provided to ABC News.

The Washington Post first reported the installation.

The NSA’s general counsel is a career civil service position and not an appointee position. Anyone in that post would continue on regardless of a change in administrations. They could only be removed under the same guidelines in place for other civil servants. There is a probationary period and tenure policy in place.

Online vacation rental marketplace Airbnb is reviewing, and potentially canceling, reservations in Lansing, Michigan, ahead of planned protests at the Michigan Capitol building.

“If we confirm that guests are associated with a violent hate group or otherwise not allowed on our platform for violating certain community policies prohibiting violence or engaging in criminal activity, we will cancel those reservations and ban them from Airbnb,” a company spokesperson said. “We are in contact with Governor Whitmer’s team, Mayor Schor and Chief Daryl Green about this plan, and if appropriate, we may bring information to the attention of local law enforcement.”

Airbnb’s efforts in Lansing are similar to its efforts in Washington, D.C. as the company seeks to identify people who have used their site and may pose a risk of violence ahead of planned protests.

“Downtown [Lansing] is a vibrant neighborhood and residents and businesses there should feel confident knowing that the Lansing Police Department is working closely with the Michigan State Police, Ingham County Sheriff’s Department and other police agencies to ensure these planned events remain peaceful,” said Lansing Mayor Andy Schor. “Airbnb has always been a fantastic partner with the U.S. Conference of Mayors, and this effort continues to demonstrate their civic mindedness and high standards of quality."

Residents of downtown Lansing should stay inside and avoid demonstrations, said Schor.

As rioters roamed the Capitol last Wednesday, freshman progressive Rep. Cori Bush tweeted she would introduce a resolution calling for the expulsion of GOP members of Congress who, she said, "incited this domestic terror attack through their attempts to overturn the election."

Bush confirmed in a tweet Sunday she’d be introducing a resolution on the House floor Monday seeking to expel lawmakers who, she said, "tried to overturn the election and incited a white supremacist coup attempt that has left people dead" arguing they violated they the 14th Amendment.

"We can’t have unity without accountability," Bush added.

House Speaker Nancy Pelosi in her letter to colleagues Sunday outlining next steps in removing Trump from office also asked Democrats for their views on Section 3 of the 14th Amendment that calls for the removal of anyone who has "engaged in insurrection or rebellion." The section effectively disqualifies those who engage in insurrection against the Constitution of the United States from holding office.

Similar calls are being made in the Senate with Sen. Sherrod Brown, D-Ohio, calling on the U.S. Senate to expel Sens. Ted Cruz, R-Texas, and Josh Hawley, R-Mo., if the senators refuse to resign in the aftermath of the assault on the Capitol.
