Former Sen. Blanche Lincoln, an Arkansas Democrat, will join the lobbying push to advance President Trump’s U.S.-Mexico-Canada Agreement on trade through Congress. She’ll be a spokeswoman for an ad hoc group called Farmers for Free Trade.

“Congressional approval of the United States-Mexico-Canada Agreement is a top priority for our nation’s agriculture industry and I’m pleased to have the opportunity to join the voice of America’s farmers on the importance of North American trade,” Lincoln said in a statement Wednesday.
