The country’s immigration enforcement officers launched a website Tuesday demanding that President Trump do more to clean up their agency, saying he has left the Obama team in place and it’s stymying his goal of enforcing laws on the books.

U.S. Immigration and Customs Enforcement supervisors in Philadelphia banned officers from wearing bulletproof vests during an operation in the dangerous “badlands” section in the city’s north for fear of offending the immigrant community, according to a new website, JICReport.com.

Meanwhile, officers in one Utah city are required to give city officials seven days’ heads-up before arresting anyone — and by the time they go to make the arrest, the immigrants they are targeting have taken off, the website says.

Compiled by the National ICE Council, which represents ICE officers, the website is part whistleblower and part primal scream for Mr. Trump to pay attention to a group of people who were among his staunchest backers during the presidential campaign.

“ICE Officers grudgingly admit that the only President they ever endorsed hasn’t kept his word, and many officers now feel betrayed,” the officers say on the website.

National ICE Council President Chris Crane, in an open letter to Mr. Trump, posted on the site, said he finds himself regularly having to defend the president to ICE officers who backed Mr. Trump during the campaign but now feel “stab[bed] in the back” by the administration.
