Paul RyanPaul RyanChaffetz says he'll vote for Trump The Trail 2016: Comeback in the works? Liberal groups call for delaying cures bill to next year MORE (R-Wis.) this fall.
Kaleka got into politics after his father, the head of a local Sikh temple, was killed by a white supremacist in 2012. He generated some buzz when he first got in the race, but his campaign never took off.
