Former Marine fighter pilot Amy McGrath announced that she will challenge Senate Majority Leader Mitch McConnell for his seat in 2020.

McGrath, 44, previously launched an unsuccessful bid for the Kentucky House in 2018, losing with 47.8% of the vote to her Democratic rival. Her decision to join the race makes her the first serious challenge to the 77-year-old Republican, who has served as a senator since 1985.
