Airports coast to coast are seeing major delays, HOURS-long security lines, and missed flights because of the Democrats’ DHS shutdown. SAVE SPRING BREAK. REOPEN DHS NOW.
The Atlanta airport has been crazy lately. These are pics from today

The Democrat DHS Shutdown has Consequences for American Citizens and Hardworking Families Our Cybersecurity Agency (@CISAgov) has lost hundreds of workers who have been furloughed. We have training for weapons of mass destruction, for detecting bombs and terrorist activities across the country, many of whom work with our local law enforcement, who have been furloughed and are not on duty today. The Democrat Party is damaging families long-term to make a political point when it has no effect on what we are doing for immigration enforcement every single day, because that agency is funded.

Nothing will stop us from making America SAFE again. Under the leadership of President Trump, DHS is delivering the most secure border in history, removing dangerous criminal illegal aliens, and making our communities safer for generations to come. Recent @ICEgov arrests include:

FEMA was in the final stages of reviewing applications to ensure proper oversight when Democrats shut down the government putting significant portions of the FEMA staff on administrative leave. No funds have been awarded yet under the FIFA World Cup Grant Program. The longer DHS goes without funding, the less prepared our nation will be for threats at the FIFA World Cup and America 250. This Democrat shutdown directly impacts DHS’s ability to keep Americans safe at these events and our national security. Democrats must end this shutdown now and let DHS get back to our mission of protecting the Homeland.

Today, @POTUS Trump directed @FEMA and @EPA to provide emergency assistance to the District of Columbia as they work to protect people from the effects of the recent spill in the Potomac. @EPALeeZeldin and I will stay in close contact to ensure coordinated federal support to the District.   FEMA is deploying a team to support incident management, working directly with local officials and federal partners to coordinate federal resources. EPA will lead the federal response while @DHSgov and FEMA leverage all our resources to ensure the cleanup is swift and effective. Even as Democrat politicians shut us down and these men and women go without pay, DHS is committed to providing much needed aid to the Americans impacted by this disaster. We will not let our citizens suffer without help.

DHS, FEMA, CISA, USCG, and our other federal partners are closely monitoring conditions and coordinating with state and local partners to ensure readiness. Governors remain in the lead, and we stand ready to support. Every American in the path of this storm should take steps to prepare and protect themselves from the elements.
