Former Vice President Mike Pence and former President Donald Trump will campaign in dueling rallies in Arizona on Friday as they support rival candidates with radically different visions of the Republican Party. Next week, they will again cross paths as they present speeches on the same day in Washington, DC.

The events indicate that Pence is getting more confrontational as the two politicians may be beginning a phase where they are competing against one another in the 2024 GOP presidential primary.
