He said that it was up to Congress to fix a “broken” immigration system, just days after a bipartisan deal to overhaul policies at the southern border was stymied in the Senate.
“It certainly is a crisis and, well, we don’t bear responsibility for a broken system,” Mr. Mayorkas said. “And we’re doing a tremendous amount within that broken system. But fundamentally, fundamentally, Congress is the only one who can fix it.”
Mr. Mayorkas, the first Latino to run the department, has testified before Congress more than any other member of President Biden’s cabinet — a total of more than two dozen times. He has told House Republican officials that their effort to impeach him will not affect the work he is doing and has maintained that he will not resign if their push is successful.
In a January letter to Representative Mark E. Green, Republican of Tennessee and the chairman of the Homeland Security Committee, Mr. Mayorkas said the drive to impeach him had not shaken him.
“I assure you that your false accusations do not rattle me and do not divert me from the law enforcement and broader public service mission to which I have devoted most of my career and to which I remain devoted,” he wrote.
