Cruz’s campaign issued a statement Monday evening, saying the Texas senator had accepted two invitations to debate in Indianapolis this week in events hosted by WRTV and WIBC.

The Cruz campaign suggested Trump was “afraid” to debate in the state, where the businessman has led by single digits in several polls released this month.

“Donald Trump continues to cower in Trump Tower, afraid to defend his positions,” the campaign said, arguing that Trump “has no answer” on how he’d carry out his campaign promises.

The push to pressure Trump comes a day after the campaigns of Cruz and John Kasich announced a joint effort in several key upcoming states to deny Trump the needed 1,237 delegates to clinch the nomination.

Cruz will have a clear path in Indiana, where he’s the closest to Trump in polls; while his campaign announced it would stand down in Oregon and New Mexico, clearing the way for Kasich.
