Senate set for floor showdown over Trump border wall
GOP senator: I'd support Kasich over Cruz
Sen. Jeff Flake (R-Ariz.) suggested Tuesday that out of the party's remaining presidential field, he would be most likely to support Ohio Gov. John Kasich.
"If I were Kasich, I'd do exactly what he's doing. Get to the convention with some delegates," he told reporters.
Flake, who was asked if Republicans face a choice between Cruz or Trump, suggested GOP voters have a third option in Kasich.
"He certainly would have been more likely than Ryan, simply because he is running and he has delegates," he added, referring to Speaker Paul Ryan (R-Wis.).
Ryan is expected to give a speech on Tuesday afternoon ruling out a presidential bid after weeks of speculation about his plans.
Flake said his comments are not an endorsement of Kasich.
The Arizona Republican - who has repeatedly raised concerns about Trump's impact on the party - previously endorsed Sen. Marco Rubio (R-Fla.), who ended his presidential bid after losing his home state's primary.
