US Capitol Police to increase security over Iran conflict

House Sergeant-at-Arms William McFarland told lawmakers Monday to expect an increase in security on Capitol Hill after the United States and Israel launched missiles at Iran over the weekend.

McFarland said the United States Capitol Police have not "identified any specific or credible threats" to the Capitol, but it comes as the FBI probes whether a shooting in Austin, Texas over the weekend was an "act of terrorism." 

“There will be heightened security measures and a noticeable increased police presence across the U.S. Capitol campus," McFarland said, per Politico. “While the USCP has not identified any specific or credible threats, these measures have been put in place out of an abundance of caution."

The strikes, which started Saturday and continued Sunday, resulted in the death of Iranian Supreme Leader Ayatollah Ali Khameini. Iran's military has since conducted counterstrikes, inflicting casualties across the Middle East, including the deaths of four U.S. service members.

Defense Secretary Pete Hegseth has also said the U.S. is keeping an eye out for any signs of sleeper-cell activity or other violence inspired by the conflict in the Middle East and that agencies are prepared to respond if any attacks do happen.
