Did the U.S. military arrest members of Congress at the White House? No, that's not true: This did not happen, and the video making the claim seemingly used the title for clickbait.
The claim appeared in a video posted to Facebook published on June 9, 2022. The title of the video is:

This is what the post looked like on Facebook at the time of writing:

The audio in the video came from a recording posted earlier in June 2022. It features conspiracy theorist Charlie Ward and others. However, the hosts do not seem to claim that the military arrested Congress at the White House -- although they do reference debunked ideas, including some from the "2000 Mules" documentary.
Congress meets at the Capitol, not the White House, which is where the president primarily resides. On June 9, 2022, the day the post was published, members of Congress were working, not under arrest. In particular, the widely broadcast hearing by the House Select Committee to Investigate the January 6th Attack on the United States Capitol was aired that night. There was also a congressional hearing held on June 10, 2022, the day after the post was made and after all the members of Congress were supposedly arrested.
There are also no reports that members of Congress were arrested by the military. Lead Stories used Google to search for "White House Congress arrest," "military arrests Congress" and "Congress White House military" and did not find any results.
