Immigration hardliner, who was seen as a rising star, Julie Kirchner has resigned from her role within the Trump administration.

According to The Daily Caller:

Julie Kirchner, once viewed as a rising star in the Trump administration, resigned from her position as ombudsman of United States Citizenship and Immigration Services (USCIS), according to an internal email.

Kirchner offered her resignation to President Donald Trump this week, according to an email distributed to staffers Monday by acting Homeland Security Secretary Kevin McAleenan. The email was first obtained by Buzzfeed News. It’s not yet clear why Kirchner is resigning, and the Department of Homeland Security did not respond to a request for comment from the Daily Caller News Foundation.

Kirchner’s resignation, nonetheless, appears to mark the end of her career in the Trump administration, despite being previously considered for one of the White House’s top immigration positions.

She first joined the Trump administration in early 2017, becoming an advisor to McAleenan, who was then the acting commissioner of Customs and Border Protection. Trump in May of that year appointed Kirchner as ombudsman of USCIS — a position that helps immigrants who face issues with the agency, such as applicants who have been rejected or are dealing with long processing times. As USCIS ombudsman, she was also in charge of preparing annual reports of the agency to Congress.

Kirchner worked for the Federation for American Immigration Reform before joining the Trump administration in 2017.
