'We want to make sure that we don't wish we didn't go far enough,' Peter Gaynor tells 'America Reports'

Acting Homeland Security Secretary Peter Gaynor told "America Reports" Monday that there is a "heightened sense of alert" surrounding the security preparations for Joe Biden's inauguration amid reports U.S. defense officials are concerned about a potential insider attack from service members brought in to protect the transfer of power.

Washington, D.C. is taking a defensive posture ahead of Inauguration Day. Approximately 25,000 National Guard troops have been sent to the capital. at the behest of the Secret Service. 

According to the Associated Press, Army Secretary Ryan McCarthy said on Sunday that officials are alert for a potential threat.

Gaynor said that following the deadly Jan. 6 riot at the Capitol, the FBI determined it would be a "prudent move" to vet each National Guard soldier sent to defend the inauguration.

And to make sure that, again, we have a peaceful transfer of power, we want to make sure that, you know, we don't wish we didn't go far enough. [We have an] impressive array of men and women out there ready to make sure that that transfer happens peacefully."
