 for Kimberly Cheadle to make sure that she appears on Monday. I have a statement here from the Oversight Committee. An Oversight Committee spokesperson says a subpoena would, quote, head off any attempt by DHS to backtrack from her appearance on Monday. Intelligence officials also now confirming former President Trump's Secret Service was enhanced some weeks ago due to an alleged Iranian plot to kill the GOP nominee, a plot they say is unrelated to Saturday's attack.
