Donald Trump’s team is expected to announce its latest cabinet pick Tuesday, nominating Rep. Tom Price to be secretary of Health and Human Services, according to reports from the Guardian and Washington Post.

Price, who serves as chairman of the House budget committee, is an orthopedic surgeon and policy wonk. He is considered a staunch opponent of Obamacare and could prove crucial in Trump's efforts to dismantle the Affordable Care Act if he's confirmed, the Guardian and Post reported, citing unnamed sources. The expected nomination was first reported by the Atlanta-Journal Constitution, citing a dozen unnamed Republican sources.

Vice President-elect Mike Pence, who is leading Trump’s transition team, told reporters Monday night to expect “a number of very important announcements tomorrow." He didn't elaborate on the announcement.

Price, 62, received his doctorate from the University of Michigan and started his career as an orthopedic surgeon in Roswell, Ga. (Two decades later, he ran for office as a Republican. He was elected to the State Senate in 1996.

As a state senator, Price served on committees for health and human services, consumer affairs and education, among others. The legislature’s website states that Price successfully sponsored legislation increasing safety for children in Home Childcare Facilities, which passed.

In 2004, he ran for the Congressional seat for the same district in northern Georgia and has held that seat since. Price replaced Paul Ryan as the House budget committee chairman, when the Wisconsin representative became speaker of the House.

Price describes himself as a fierce opponent of government waste committed to lower spending and limited government. When the Obama administration announced premium hikes last month, Price called Obamacare a “broken, unaffordable law” in a statement.

“While President Obama and Democrats have the audacity to tout Obamacare’s ‘success,’ the cold hard facts and figures prove the opposite is true,” he said in the statement.

An opponent of abortion, he cosponsored the Pain-Capable Unborn Child Protection Act, which bans abortions after 20 weeks. The legislation passed in the House, but not the Senate.
