(FOX NEWS NETWORK) -- Ohio Gov. John Kasich plans to suspend his Republican presidential campaign, Fox News has learned. 

The expected announcement comes after the underdog candidate abruptly canceled an appearance in the D.C. area. He plans to make a formal statement Wednesday afternoon in his home state. 

A Kasich spokesman said the Republican presidential candidate will speak in Columbus at 5 p.m. ET.

The governor originally had planned to speak with reporters at the Dulles airport in Virginia ahead of finance events Wednesday, but did not show up. The campaign later confirmed he was not going to Dulles.

The decision comes after Texas Sen. Ted Cruz suspended his campaign Tuesday night, having finished a distant second in the Indiana primary.

Kasich placed last in that contest, though his campaign initially said Tuesday night they would keep going – until a candidate has the requisite 1,237 delegates.

Donald Trump has not yet reached that number. 

Despite the change in plans Wednesday, the Kasich campaign was making fundraising appeals in the aftermath of the Indiana results, continuing to cast the Ohio governor as the only one who could derail Trump at the party convention -- and the best candidate to face likely Democratic nominee Hillary Clinton in the fall. 

The campaign even invoked Star Wars Day, calling him the "only hope" on Twitter.
