President Trump has nominated Indiana health commissioner Jerome Adams to become the next surgeon general.

If Adams wins Senate confirmation, he would succeed Vivek Murthy as the nation’s top doctor. Murthy, who was appointed by former President Barack Obama, was removed from the post in April.

Adams was appointed to his Indiana post by Vice President Mike Pence when he was governor of Indiana.

Adams was appointed in fall 2014 right before a major outbreak of HIV connected to needle use from opioid abuse in rural Indiana. Pence was criticized for taking too long to set up a needle exchange to help alleviate the crisis.
