President Donald Trump has ordered federal immigration agents to assist with airport security at airports during the partial government shutdown. The move comes amid concerns about hourslong waits and angry screeners due to missed paychecks. Immigration agents may guard exit lanes or check passenger IDs, freeing them to work screening lines. The White House border czar, Tom Homan, has been named to lead this effort. The Senate is expected to advance the nomination of Sen. Markwayne Mullin, R-Okla., to be Trump’s next homeland security secretary. The president has made clear that he plans to continue with this plan without agreement on a bill to fund the Department of Homeland Security.
