US Department of Homeland Security is expected to buy up to $20m in gloves amid criticism of the president’s immigration crackdown.

The administration of United States President Donald Trump is planning to spend tens of millions of dollars to equip federal immigration agents with gloves capable of delivering electric shocks.

According to a notice posted on Monday, the Department of Homeland Security has estimated it will invest between $10m and $20m in such gloves by the end of March 2027.

The devices are known as the CT-G5 G.L.O.V.E., an acronym that stands for “Generate Low Output Voltage Emitter”. They are currently used by some jails and police departments.

Their manufacturer, Compliant Technologies, says the gloves are used to “quickly distract with small uncomfortable electrical pulses” when applied to a person’s skin. The Department of Homeland Security indicated they would be used for “distraction and de-escalation”.

A user manual states the gloves can deliver a maximum of 380 volts, which “inhibits/distracts the subject from performing coordinated muscle movement”.

The planned purchase has already sparked a backlash among rights advocates, who fear the gloves will be used to harm protesters and immigrants in the department’s custody.

The Department of Homeland Security oversees an array of agencies, including Immigration and Customs Enforcement (ICE), which has led Trump’s campaign of mass deportation.

Monday’s announcement specified that ICE has a requirement to make the purchase and distribute the gloves to agents within Enforcement and Removal Operations, one of its subsidiaries, and Homeland Security Investigations.

But ICE has faced increasing criticism for its tactics, including accusations of racial profiling and excessive force.

At least four people have been shot dead during encounters with ICE agents since the start of this year. Dozens more have died in ICE custody.

On Wednesday, the National Immigration Law Center (NILC) issued a statement criticising the anticipated glove purchase, calling it a path to further violence against vulnerable communities.

It also noted that, in June, the Republican-led Congress passed tens of billions of dollars in ICE spending as part of the Secure America Act.

“This is a rogue agency with an $80 billion slush fund that allows them to concoct and fund new ways to visit cruelty upon our communities,” NILC President Kica Mantos said in the statement. “Arming poorly trained agents with electric shock gloves to inflict pain on our neighbors is disgusting and barbaric.”

The Department of Homeland Security offered no immediate response to The Associated Press news agency, one of the first news outlets to report on the story.

The founder and CEO of Compliant, Jeff Niklaus, told the publication in an email, “Unfortunately, we are unable to speak on this subject.”

Compliant has argued in the past that its devices are “humane” and do not cause injury.

“The technology is safe as it does not penetrate the subject’s body, while also allowing other officers to grab the individual being stimulated with no fear of feedback into their bodies,” the manufacturer says on its website.

However, Compliant recommends avoiding use of the device on “higher risk” individuals, including the elderly, small children, pregnant people and those with severe disabilities. Officers must also complete a course to use the gloves and be recertified every two years, according to the company.

The notice, listed as a no-bid contract, could be published by Friday.
