Former US ambassador to Ukraine who resigned in protest launches run for Congress in Michigan

Bridget Brink, who stepped down as U.S. ambassador to Ukraine this year in protest of what she said was President Donald Trump's unfair treatment of the the war-torn country, announced Wednesday that she's running for Congress in one of Michigan's most competitive districts. The longtime diplomat, who previously held high-ranking State Department roles in other former Soviet and Eastern European countries, is casting herself as a public servant as she runs in next year's midterm elections, when her Democrats hope to win control of the House.
