FBI Director Christopher Wray is set to warn Congress on Thursday of his concerns over potential bad actors carrying out attacks on U.S. soil due to events overseas.

"Our most immediate concern has been that individuals or small groups will draw twisted inspiration from the events in the Middle East to carry out attacks here at home,” Wray is set to tell the House Appropriations Committee, according to a transcript of his opening statement obtained by ABC News. "But now increasingly concerning is the potential for a coordinated attack here in the homeland, akin to the ISIS-K attack we saw at the Russia Concert Hall a couple weeks ago."

In his testimony, Wray will also urge Congress to reauthorize Section 702 of the Foreign Intelligence Surveillance Act, which lays the groundwork for the government to be able to collect the communications of non-Americans overseas on U.S.-based platforms without the use of a warrant.

The effort was torpedoed in the House by former President Donald Trump and his allies on Wednesday after Trump urged GOP members to "Kill FISA" in a post on his Truth Social platform.
