(WASHINGTON) — A dozen Army National Guard members have been removed from the inauguration security mission, including two who were sent home after vetting for extremist links found an “inappropriate” text and comment, the Pentagon said oTuesday.

Each of the 25,000 National Guardsmen now in Washington assisting with security at Wednesday’s presidential inauguration is being vetted by the FBI.

Each of the dozen Guard members has been sent back to his or her home state for later investigation either by their chain of command or law enforcement, officials said.

Two of the Guard members had made what Pentagon officials called an “inappropriate” text and comment, presumably of a political nature, while the other 10, officials said, had engaged in questionable behavior unrelated to extremism.

One of the Guard members was reported through the chain of command, the other was reported through an anonymous tip line, according to Jonathan Hoffman, the chief Pentagon spokesman.

The other 10 Guard members were flagged by the FBI’s broad vetting process that looks at more than just whether there are ties to extremism.

“These are vetting efforts that identify any questionable behavior in the past or any potential link to questionable behavior, not just related to extremism,” Hoffman said.

“If there’s any identification, or anything whatsoever that needs to be looked into, out of an abundance of caution we automatically pull those personnel off the line, and make sure that they’re not part of the mission set,” said Gen. Daniel Hokanson, the Chief of the National Guard Bureau, at a Pentagon news conference. “And in certain cases we make sure that we get them sent home.”

Hoffman said that Guard commanders are immediately removing any members who are reported to have engaged in questionable behavior and worry about follow-on action later .

“We’re not even asking what the flag was we’re just removing them,” said Hoffman.

“We’re not taking any chances,” said Hoffman. “We’ll ask questions later and we will ascertain whether any action needs to be taken by the law enforcement or by their chain of command.”

No details were immediately available about which state Guard units the dozen members belonged to or about the nature of of the alleged ties.
