LOUISVILLE, Ky. (WDRB and CNN) -- CNN reports President-elect Trump has chosen Elaine Chao as his choice for transportation secretary, according to an official briefed on the matter.

Chao is the wife of Senate Majority Leader Mitch McConnell of Kentucky and a former secretary of labor under President George W. Bush.

Politico also cites multiple sources saying Chao is the transportation pick, after she met with Trump at Trump Tower last week. Trump's transition team said then that Chao discussed labor and transportation policy with the president-elect.

A formal announcement from the Trump transition team is expected Tuesday afternoon.

Chao is the first Asian-American woman to hold a cabinet position. She served as an adviser to the Trump campaign.
