The House Oversight Committee, led by Chairman James Comer (R-Ky.), has issued subpoenas to the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) and the White House Office of Gun Violence Prevention as part of an investigation into potential collusion between the Biden administration and gun control groups. The inquiry is centered around the pending litigation City of Chicago v. Glock, with allegations that the White House coordinated with anti-Second Amendment plaintiffs.
