LOS ANGELES (AP) — In just 2½ years, the Trump administration has put its stamp on the nation’s immigration court system, appointing more than 4 in 10 judges while dramatically expanding the bench and issuing new rules that make it harder for migrants to win their cases and stay in the country.

An Associated Press analysis shows that President Donald Trump’s administration has appointed at least 190 immigration judges, accounting for 43 percent of the total.

The hires helped expand the immigration bench by more than 100 since September 2016; by comparison, President Barack Obama had a net gain of fewer than 50 judges from 2010 to 2016.

The AP analysis also found that Trump has continued a trend from past administrations in hiring large numbers of former military lawyers and Immigration and Customs Enforcement attorneys as judges. Nearly 1 in 5 sitting judges appointed under Trump was a military lawyer, and half previously worked for ICE.

The administration has ramped up staffing in a bid to reduce enormous delays in the overwhelmed immigration court system, which has nearly 900,000 cases. Immigrants seeking to stay in the country often wait years for a hearing, let alone a decision.

Critics say Trump’s selections are no coincidence at a time when the president is trying hard to curtail immigration, especially for the tens of thousands of Central Americans arriving at the border in hopes of winning asylum.

“My thinking is they want to bring in people who they think have the professional experience that will lead them to interpret the law in the way the attorney general wants it to be interpreted, which is, basically, Central American domestic violence and gang claims are not valid asylum claims,” said Jeffrey Chase, a former immigration judge.

Immigration judges — who are employed by the Justice Department, not the judicial branch — make critical decisions about who gets asylum and green cards to stay in the United States and who must return to their home countries, shaping the lives of immigrants and their families and the fate of Trump’s crackdown.

The judges have been taking a harder line under Trump than in the previous administration, denying 65 percent of asylum cases during the 2018 fiscal year, compared with 55 percent two years earlier, according to data from the Transactional Records Access Clearinghouse at Syracuse University.
