Former state Sen. Kelli Ward, who is challenging Arizona Sen. John McCain in the Aug. 30 Republican primary, won her second congressional endorsement Monday.

Kentucky GOP Rep. Thomas Massie endorsed Ward and donated $2,000 to her campaign.

A statement from the Ward campaign called Massie a “major figure in the so-called liberty movement begun by former Texas Congressman Ron Paul who has also endorsed Ward.”

“We need Dr. Ward in the U.S. Senate to stand with Rand Paul and Mike Lee,” Massie said in a statement, referring to the junior senators from Kentucky and Utah.
