Republican front-runner Donald Trump unleashed Friday afternoon on his political rivals in one of his trademark Twitter tirades.

Trump first went after his chief GOP rival, Sen. Ted Cruz (R-Texas). Calling the Texas senator a liar, the real estate mogul said that Sen. Lindsey Graham’s (R-S.C.) endorsement of him would only serve as a “jinx” in the campaign.

Trump next slammed former Red State Editor Erick Erickson, one of the de facto leaders of the Never Trump movement.

Erickson issued a response.

The billionaire quickly moved to knock the Club for Growth, an apparent response to the group going after him in Utah.

Moments later, Trump turned his attention back on Cruz.

He then slammed Mitt Romney for backing the Texas senator in Utah.

Finally, Trump concluded his rant asking viewers to boycott Fox News host Megyn Kelly’s show.
