The top Justice Department official who defended the president’s health care law at the Supreme Court is leaving his job.

Solicitor General Donald Verrilli Jr. is ending his five-year tenure as the administration’s chief lawyer at the high court, President Barack Obama said in a statement Thursday.

Verrilli, 58, made the principal argument in defense of the health law against a major challenge in 2012 and an attack on subsidies for low-income Americans last year. The 2012 case took place in the midst of Obama’s re-election campaign, with the signature domestic achievement of his first term essentially on trial at the Supreme Court.

The Senate will begin work thisweek on its health-related appropriations bill, which it hopes will make it to a floor vote this year.

The health panel of the Senate Appropriations Committee, led by Sen. Roy Blunt (R-Mo.), will meet Tuesday to mark up its spending bill. That bill, which includes funding for the Departments of Labor and Health and Human Services, passed out of committee last year, but ultimately did not make it for a full floor vote.
