MADISON, Wis. (AP) — Gov. Scott Walker says he may join Republican presidential hopeful Ted Cruz on the campaign trail in Indiana.

Walker told reporters during a question-and-answer session Monday that he hasn't gotten any requests from Cruz yet but there's a possibility he might join the candidate on Sunday. The governor said hadn't heard about any specific event yet, however.

Walker has enjoyed a resurgence of sorts within Republican circles after helping Cruz win Wisconsin's GOP presidential primary earlier this month.

Indiana's primary is May 3.
