From NBC News:
Ohio Gov. John Kasich will suspend his presidential campaign on Wednesday, a senior campaign adviser tells NBC News.
Kasich cancelled a press conference in Virginia earlier in the day and announced he would make a statement in Columbus, Ohio, Thursday afternoon.
The decision comes one day after Kasich finished a distant third in the Indiana primary. Top campaign aides vowed that the governor would stay in the race, even after Ted Cruz, who formed an informal alliance with Kasich, suspended his campaign.
