Republican National Committee chief of staff Sara Armstrong is leaving her post for a position at the U.S. Chamber of Commerce.

Armstrong is leaving her job and will take a senior position at the U.S. Chamber of Commerce, an RNC official told the Washington Examiner.

Armstrong came to the RNC in January, shortly after President Trump's inauguration. She had worked at the RNC for a number of years, serving as chief executive of Trump's inauguration committee, vice president of the GOP convention for the 2016 election and chief operating officer for the 2014 election cycle.

Armstrong had previously served as deputy chief of staff with the RNC during the 2012 election cycle as well.

Thomas Donohue, president and CEO of the U.S. Chamber of Commerce, said in a statement that Armstrong will work with Scott Reed and Rob Engstrom and assumes the position of vice president of political affairs and federation reslations.

"Never has the voice of business been more important than today," said Thomas J. Donohue, president and CEO of the U.S. Chamber of Commerce. "With Sara, Scott, and Rob leading our political program, we're assured the Chamber's voice will be heard and voters will learn where candidates stand on issues impacting free enterprise."
