President Trump is mulling Health and Human Services Secretary Alex Azar as a possible replacement for Attorney General Jeff Sessions, according to a new report.

Citing unnamed sources in the White House, the Wall Street Journal reported that Azar and four others are on the shortlist, including Transportation Department general counsel Steven Bradbury, former Attorney General Bill Barr, Deputy Secretary of State John Sullivan and Janice Rogers Brown, a retired appeals court judge from the District of Columbia Circuit.

Trump has criticized Sessions’ decision to recuse himself from the special counsel’s probe into whether the Trump campaign colluded with Russia to influence the presidential election. Suspicions have grown over whether Sessions will resign from his position or be asked to resign.

The official who replaces sessions would need to be confirmed by the Senate, even if they have been previously confirmed for other positions.

Azar was confirmed as Trump's health secretary in January. He had served as deputy secretary of HHS under former President George W. Bush. He also is a former top executive for pharmaceutical giant Eli Lilly.

In his role as HHS secretary he has prioritized lowering the prices of prescription drugs and reducing premiums for Obamacare customers.
