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.

The danger to the public and to law enforcement officers from explosive devices during expected upcoming protests "is substantial," the Federal Bureau of Investigation warned in a new awareness bulletin obtained by ABC News on Friday.

The document is full of photos of devices used in the last eight months against civilian and law enforcement targets during public demonstrations.

"Devices targeting infrastructure also increased following violent activity during this time period," the bulletin states.

The FBI now wants to make first responders aware of what has been deployed in the past and what they might encounter during protests linked to the presidential inauguration on Jan. 20.

"The danger posed to law enforcement officers and the general public from the all the tactics listed is substantial," the bulletin states. "If a suspicious item is reasonably believed to contain explosives, an IED, or other hazardous material, DO NOT touch, tamper with, or move the item. Only bomb disposal personal should handle any suspected devices that are located."

An internal FBI bulletin obtained by ABC News earlier this week stated that armed protests are being planned at all 50 state capitols as well as at the U.S. Capitol in Washington, least through Inauguration Day.

The warning comes after suspected pipe bombs were found last week outside both the Democratic National Committee and the Republican National Committee headquarters, just a few blocks from the Capitol where pro-Trump rioters stormed the building.
