The US government has hired 50,000 employees since President Donald Trump took office, his top personnel official said, with the new staff largely in national security positions reflecting the administration’s policy focus.

Axar.az informs, citing Reuters, the bulk of the new hires work at Immigration and Customs Enforcement, said Scott Kupor, the federal government’s human resources director, in an interview on Thursday night.

The staff changes are part of Trump’s campaign to recast the government while sharply cutting other federal jobs.

“It’s about reshaping the workforce to focus on the priorities that we think are most important,” Kupor said.

The administration brought on the new employees while freezing hiring and laying off workers in other parts of the government, such as the Internal Revenue Service and the Department of Health and Human Services.

The administration expects to shed about 300,000 workers this year, Kupor said in August.
