In a sign of plans to roll back President Obama's health care law, President-elect Donald Trump plans to nominate Georgia congressman and outspoken Obama critic Tom Price to be secretary of health and human services, officials said.

Ex-House Speaker Newt Gingrich, a frequent Trump adviser, tweeted that Price will make a "great" HHS secretary, and "is the right leader to help Congress replace Obamacare."

A person familiar with the transition confirmed the planned nomination, speaking on condition of anonymity until the announcement is made official, perhaps on Tuesday.

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.

A six-term member of Congress and an orthopedic surgeon, Price is a frequent critic of the health care law that Obama signed in 2010.

“Premiums have gone up, not down," he has said. "Many Americans lost the health coverage they were told time and time again by the president that they could keep. Choices are fewer.”

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 joined scores of Congressional members in cosponsoring the Pain-Capable Unborn Child Protection Act in 2015, which bans abortions after 20 weeks. The legislation passed in the House, but not the Senate.
