WASHINGTON — House Republicans are moving quickly to emphasize Vice President Kamala Harris’s role in the Biden administration’s handling of the U.S. border with Mexico, passing a resolution Thursday that condemns her performance in the job.

All House Republicans and six Democrats in tough re-election races voted for the resolution, which is purely symbolic. President Joe Biden tasked Harris early in his administration with addressing the root causes of migration.

Border crossings eventually became a major political liability for Biden when they reached historic levels. Since June, when Biden announced significant restrictions on asylum applications at the border, arrests for illegal crossings have fallen.

White House press secretary Karine Jean-Pierre said migrant encounters between U.S. ports of entry have dropped more than 55 percent and are now lower on average than they were at the end of Trump’s term. Republicans say Harris did not do enough to clamp down on illegal immigration in a role they characterized as “border czar.”

“The result of her inaction has been record high illegal crossings, overwhelmed communities, and an evisceration of the rule of law,” said House Speaker Mike Johnson, R-La. The House vote showed some early signs of cracks in the confidence that Democrats have so far bestowed on Harris.

The six Democrats who voted for the resolution — Reps. Yadira Caraveo of Colorado, Henry Cuellar of Texas, Don Davis of North Carolina, Jared Golden of Maine, Mary Peltola of Alaska and Marie Gluesenkamp Perez of Washington state — were all members from battleground districts and had previously been critical of Biden on the border.

The measure called for “elected officials who understand the gravity of the crisis at the border and who will execute the policies to fix the border crisis.” “This isn’t about any one person — it’s about our border not being secure and fentanyl destroying Alaska communities,” Peltola said in a statement.

Most House Democrats tried to defend how Harris has handled the job. Democratic leader Hakeem Jeffries of New York said the resolution was “fake and fraudulent” and that Harris was never appointed “border czar,” as the measure stated.

Rep. Pramila Jayapal of Washington state, who is the chair of the Congressional Progressive Caucus, said Harris “was narrowly tasked with developing agreements that could help bring government and private sector investments to those countries that are sending migrants to the United States.”

Jayapal said Harris successfully recruited “billions” of dollars in investments for Mexico, Guatemala, El Salvador and Honduras.

Democrats also repeatedly pointed out that Republicans rejected a border and immigration deal that the White House negotiated with Senate GOP leadership earlier this year.
