U.S. Border Patrol Chief Michael Banks announced that nearly all illegal immigrants detained will be charged a $5,000 "apprehension fee."

In a post on X on Thursday, Banks said illegal immigrants ages 14 and older who entered the country without inspection will face a fee, a provision included in the "big, beautiful bill," which President Donald Trump signed into law in July.

"This message applies to all illegal aliens — regardless of where they entered, how long they’ve been in the U.S., their current location, or any ongoing immigration proceedings," Banks wrote.

TRUMP'S REMITTANCE TAX AIMS TO SLOW ILLEGAL IMMIGRATION BY TARGETING THE MONEY FLOW

The warning came after a lawsuit was filed Thursday against the federal government on behalf of 21,500 immigrants facing daily penalties of $998, reaching up to $1.8 million each for staying in the U.S. illegally. 

Their lawyers argued they were attempting to comply with federal immigration laws.

The Department of Homeland Security (DHS) announced in October that migrants paroled in the U.S. would also face a $1,000 fee "to institute accountability and prevent rampant fraud of the parole system."

DHS this week launched a "holiday deal of a lifetime," offering illegal immigrants a "Cyber Monday" incentive to self-deport.

All illegal immigrants in the country could receive a free flight home and a $1,000 bonus for voluntarily leaving the country. The average cost to arrest, detain and deport someone is $17,000, according to DHS.

People in the U.S. illegally may also qualify for forgiveness of any civil fines or penalties incurred for failing to depart, DHS said, allowing the possibility for them to return legally.

TRUMP ADMIN ON PACE TO SHATTER DEPORTATION RECORD BY END OF FIRST YEAR: 'JUST THE BEGINNING'

The Trump administration previously announced it closed out fiscal year 2025 with 237,565 Border Patrol apprehensions, the fewest since 1970.

DHS Assistant Secretary Tricia McLaughlin told Fox News Digital in October that the administration was "on pace to shatter historic records" by tallying 600,000 deportations by the end of Trump’s first year back in office. 

More than two million illegal immigrants have left the U.S. this year, she said, including 1.6 million who self-deported, 515,000 deportations and another 485,000 were arrested.

Trump deployed additional personnel to the southern border after taking office and ended "catch-and-release," the practice of releasing illegal immigrants as they wait for hearings.

The Department of Homeland Security (DHS) on Friday pushed back against accusations from Arizona Democratic Rep. Adelita Grijalva, who claimed she was pepper sprayed during an immigration raid in Tucson.

In a post on X, Grijalva said she was "pushed aside and pepper sprayed" after identifying herself as a member of Congress while seeking information from officers during a U.S. Immigration and Customs Enforcement's (ICE) operation near the Taco Giro restaurant.

"ICE just conducted a raid by Taco Giro in Tucson — a small mom-and-pop restaurant that has served our community for years," Grijalva wrote. "When I presented myself as a Member of Congress asking for more information, I was pushed aside and pepper sprayed."

In a separate post, Grijalva called ICE a "lawless agency" that is "operating with no transparency, no accountability, and open disregard for basic due process."

DHS Assistant Secretary Tricia McLaughlin swiftly fired back at Grijalva's claims, saying she was never directly sprayed but merely in the "vicinity of someone who was."

"If her claims were true, this would be a medical marvel," McLaughlin said. "But they’re not true. She wasn’t pepper sprayed. She was in the vicinity of someone who was pepper sprayed as they were obstructing and assaulting law enforcement."

McLaughlin also said two law enforcement officers were "seriously injured" during the incident.

"In fact, 2 law enforcement officers were seriously injured by this mob that [Grijalva] joined," she added. "Presenting oneself as a ‘member of Congress’ doesn’t give you the right to obstruct law enforcement. More information forthcoming."

The clash also prompted the Congressional Progressive Caucus — which includes nearly 100 Democratic lawmakers — to call for a congressional investigation.

Rep. Ilhan Omar, D-Minn., a deputy chair of the caucus, denounced the incident as a "disgusting display of violence" against Grijalva and warned that it reflects "a dangerous moment for American democracy."

The dispute unfolded a day after DHS announced it had rounded up at least a dozen criminal illegal immigrants — including "child sex offenders, domestic abusers, and violent gang members" — during Operation Metro Surge in Minneapolis. 

"No matter when and where, ICE will find, arrest, and deport ALL criminal illegal aliens," McLaughlin said.

DHS and Grijalva did not immediately respond to Fox News Digital's request for comment.
