Sen. Ted Cruz (R-Tex.) waded into the contested Republican primary for U.S. Senate in Nebraska Wednesday, endorsing Midland University President Ben Sasse.

"I have gotten to know Ben Sasse, and while Nebraskans have good choices, Ben is the strongest conservative voice running for United States Senate," Cruz said in a statement distributed by Sasse's campaign. "Ben will not be just another vote in the Senate – he will be a leader in the fight to stop the Obama agenda and repeal ObamaCare from day one."

Cruz will join Sen. Mike Lee (R-Utah) and former Alaska governor Sarah Palin (R) at a rally for Sasse on Friday. Sasse is running against former state treasurer Shane Osborn (R) for Nebraska's open Senate seat.

This is Cruz's second Senate endorsement in as many weeks. He threw his support behind former state House speaker T.W. Shannon (R) in Oklahoma last week.
