GOP doubles down on impeachment push even as border numbers plummet

• The exhaustive "phase 1" investigation report describes Mayorkas as "the chief architect of the illegal immigration crisis that Americans have suffered through since January 2021."
• It's another sign of how important the border issue has become for Republicans, even as the chaos in border states has waned.

By the numbers: Monthly illegal border crossings dropped to the lowest level in two years in June — falling to under 100,000 for the first time in that time period, according to government data released Tuesday.

• Since taking office, Biden has struggled with logistical, humanitarian and political crises posed by record numbers of migrants crossing the southern border amid unprecedented migration throughout the Western Hemisphere.
• Faced with the end of a pandemic policy called Title 42, which enabled the rapid expulsion of migrants and asylum seekers, Biden imposed severe new asylum restrictions in May. The rules angered immigration advocates and some Democrats.
• Since then, border numbers have plummeted — though it is unclear how much of the decline can be attributed to the new restrictions.

• Still, the falling border numbers have not swayed Republicans from building their case for an impeachment inquiry into Mayorkas.

Zoom in: In the new report, House Homeland Security Committee Republicans — led by Rep. Mark Green (R-Tenn.) lay out familiar lines of attack against Mayorkas.

• They have latched on to the military term "dereliction of duty," which has no legal application to Cabinet members. The report cites a definition from the Manual for Courts-Martial.
• Mayorkas is accused of abusing or not enforcing immigration laws by setting up new parole programs and releasing undocumented migrants into the U.S. — a practice of multiple administrations when border resources have been overwhlemed.
• The report claims he also ignored court rulings and lied to Congress and the American people about the security of the border.
• The report initially zeroes in on the use of humanitarian parole, pointing to new programs that use parole to provide legal entry into the U.S. to certain nationalities.

• For decades, parole has been used to respond to refugee crises, but Biden has made unprecedented use of the tool.
• More than half a million people have been admitted into the U.S. through various parole programs under Biden, according to reporting by CBS News.

What they're saying: "Instead of pointing fingers and pursuing a baseless impeachment, Congress should work with the Department and pass comprehensive legislation to fix our broken immigration system," a DHS spokesperson told Axios in a statement.

• "I realize Republicans have been counting on chaos on border for months and are now panicking that the Administration policies are working, but there is no valid basis for impeachment," Homeland Security Ranking Member Bennie Thompson said in a statement.

What to watch: The new congressional report and monthly border numbers come as a federal judge considers whether to block Biden's new asylum rule, which automatically rejects from asylum most migrants who illegally cross the border and do not first seek refuge in a country they travelled through.

• The case could force the administration to dramatically change its post-Title 42 strategy.
