The Department of Homeland Security alerted staff about a recent increase in threats against employees since it started enforcing immigration laws, according to WTOP-TV.
Acting deputy secretary of Homeland Security Claire Grady notified employees in a letter on Saturday. An official with knowledge of the recent threat assessment told WTOP that the increase in threats has been attributed to the "zero-tolerance" policy that called for the arrest of immigrants illegally crossing the border.
The separation of more than 2,000 children from their parents who face criminal charges for entering the U.S. illegally sparked widespread outrage among citizens and lawmakers.
A burnt and decapitated animal was found on the front porch of a senior DHS official who lives in the Washington, D.C., area, according to an unnamed source, WTOP reported.
In recent days, about two dozen threats were issued mostly against immigration officers, an official told the news station.
What did the letter say?
The letter reportedly warned staffers of the “heightened threat against DHS employees."
“This assessment is based on specific and credible threats that have been levied against certain DHS employees and a sharp increase in the overall number of general threats against DHS employees,” Grady wrote in the letter, according to WTOP.
There have also been multiple protests against immigration laws and Homeland Security.
Homeland Security Secretary Kirstjen Nielsen was harassed over the separation of immigrant families by members of Democratic Socialists of America last week while eating at MXDC Cocina Mexicana in Washington, D.C.
“You’re eating a Mexican dinner as you’re deporting tens of thousands of people separated from their parents,” the protesters chanted.
On Friday, a group of demonstrators played audio of crying children outside Nielsen's Virginia home.
“Shame!” they chanted.
WikilLeaks published information on more than 9,000 supposed current and former Immigration and Customs Enforcement employees, according to The Washington Post, citing its important for “increasing accountability."
“People can disagree on policy,” ICE spokeswoman Liz Johnson said in a statement to ABC News, “but it is unconscionable to target our employees and advocate violence against federal law enforcement officers.”
On Wednesday, President Donald Trump signed an executive order that would keep families together during immigration proceedings.
