The move follows a similar one at Miami International Airport over the weekend.
Houston Airports released a statement on the closure that said in part:
"Due to staffing issues associated with the partial shutdown of the federal government, the Transportation Security Administration (TSA) security checkpoint and the ticketing counter in Terminal B at George Bush Intercontinental Airport closed at 3:30 p.m. on Sunday, Jan. 13, 2019, and will remain closed the rest of the day.”
Airport officials and Houston Mayor Sylvester Turner are urging passengers to arrive early for flights after the terminal closure, as more travelers will be trying to get through fewer security checkpoints.
The government partially closed down on Dec. 22, 2018, when President Donald Trump refused to sign a spending bill that did not include $5 billion for a border wall with Mexico, one of his campaign promises, and House Democrats refused to agree to a bill that included money for a border wall, saying border security was a separate issue.
