The U.S. House of Representatives is scheduled to vote Tuesday on whether to override President Donald Trump's veto of legislation that would void his declaration of a national emergency at the nation's southern border.
The vote is unlikely to reach the two-thirds majority necessary to succeed.
Trump made the declaration in February, citing what he said was a border security and humanitarian crisis to allow him to reallocate $3.6 billion from other government projects to pay for wall construction along the U.S.-Mexico border.
Both the Democrat-led House and the Republican-majority Senate approved a bill rejecting his move, with many citing objections to a president making spending decisions they said should be done by Congress.
Trump's veto was his first since taking office in 2017.
