In a sign of just how much the Republican presidential primary has turned the party on its head, Sen. Lindsey Graham will host a fundraiser on Monday in support of Sen. Ted Cruz.

A draft of the invitation, obtained first by CNN, invites guests to “honor and support a great friend of Israel and the Jewish people,” at a meet-and-greet event that will take place during the AIPAC policy conference in Washington next week.

Graham, who ended his bid for the Republican nomination last December, originally threw his support behind former Florida Gov. Jeb Bush and campaign for him in South Carolina.

Support for Cruz is an about-face for the South Carolina senator, who compared nominating GOP front-runer Donald Trump or Cruz to being shot or poisoned. He recently mocked Cruz’s unpopularity among his colleagues, saying earlier this month: “If you killed Ted Cruz on the floor of the Senate, and the trial was in the Senate, nobody would convict you.”

The move is also a sign that Cruz might be starting to gain traction with his colleagues in the Senate.

Cruz picked up his first Senate endorsement from Utah Sen. Mike Lee last week.
