Mike Pence Major 'Announcement': Will He Endorse Ted Cruz?

CHICAGO (CBS) -- Indiana Gov. Mike Pence will make a "significant announcement" today, reportedly an endorsement of GOP presidential candidate Ted Cruz.

The Indiana primary is next Tuesday, and Pence has met with all three candidates--Donald Trump, Sen. Ted Cruz and Ohio Gov. John Kasich.

According to CNN, Pence will endorse Cruz on Greg Garrison's conservative talk radio show.

Earlier this week, Kasich said he was conceding the state, clearing a path, in theory, for Cruz to derail Trump. However, that agreement didn't last long, as Kasich still encouraged his backers in Indiana to vote for him.

The state is now viewed as critical for Cruz to stop Trump from securing the nomination outright before the GOP convention this summer in Cleveland.

Cruz has been spending a tremendous amount of time in the Hoosier state and considers a Pence endorsement a key to shoring up the state's evangelical voters.

Indiana has 57 delegates. The statewide winner gets 30. The winner in each of nine congressional districts gets three apiece.
