A Texas Republican has filed articles of impeachment against Department of Homeland Security Secretary Alejandro Mayorkas, wasting little time into the new Congress to act on a GOP priority leadership has said would come after thorough investigation.

Rep. Pat Fallon (R-Texas) filed the paperwork for the resolution Jan. 3, the first day of the 118th Congress, though with delays in securing a House Speaker, the document was officially filed late Monday.

The resolution claims Mayorkas “engaged in a pattern of conduct that is incompatible with his duties,” complaining that he has failed to maintain operational control over the border.

The resolution comes amid a busy week in the Biden administration. President Biden visited the border over the weekend for the first time since taking office, pledging to deliver more resources to the officers that patrol the region.

And Mayorkas is in Mexico this week, meeting with officials there on a variety of issues, including the shared migration agreement rolled out by the Biden administration last week.

Mayorkas is also due to discuss coordination on trans-national crime with Mexican authorities. His office did not immediately respond to request for comment.

Fallon’s resolution won’t move without further action from GOP leadership, but it would otherwise jump start a process House Speaker Kevin McCarthy (R-Calif.) has treaded carefully on.

“House Republicans will investigate every order, every action and every failure will determine whether we can begin impeachment inquiry,” McCarthy said at a press conference in El Paso, Texas, in November.

Still, impeachment charges against Mayorkas were all but certain under Republican control of the House, as the DHS secretary has been a constant foil for the GOP during the Biden administration.

Republicans claim that under Biden, DHS has dismantled the border security apparatus built under former President Trump, leading to border chaos.

Most border and immigration analysts agree that increased migration due to security, economic and governance conditions in the Western Hemisphere is the primary reason for the high number of migrants encountered at the border.

And Mayorkas has taken flak both from the right and the left, as DHS has maintained many of the Trump administration’s border policies, which immigrant advocates say violate human rights.

Still, Republicans see the border as a winning issue for them, and Mayorkas is the Biden administration’s face on that issue.

Mayorkas, the first Latino to ever hold that post, has often butted heads with congressional Republicans at oversight hearings.

In April, Mayorkas clashed with Republicans on the House Judiciary Committee, including a notable exchange with Rep. Matt Gaetz (R-Fla.) over his agency’s record on deportations from the interior of the country.

That combative exchange could set the tone for impeachment proceedings.

The potential for a political circus is concerning for Republicans fresh off a nationally-televised Speaker’s race that highlighted divisions in the party.

Some Republicans have expressed reservations about going after Mayorkas without careful study. 

“You’ve got to build a case. You need the facts, evidence before you indict,” Rep. Michael McCaul (R-Texas).

“Has he been derelict in his responsibilities? I think so,” he said.
