Sen. Ted Cruz was with a fuming President Trump as Elon Musk viciously attacked his former ally online Thursday — with the Texas Republican saying the spat made him feel like he was a kid in the middle of a divorce.

Ted Cruz says he had a front-row seat to the explosive fallout between Donald Trump and Elon Musk -- revealing he was in the Oval Office with the President when it all went down.

The Texas senator urged the two former allies to reconcile as their feud over the spending bill threatens the GOP's unity and legislative agenda.
