"If we screw all this up, you better believe the American people could elect President Elizabeth Warren," Cruz warned, according to the Texas Tribune.

But, he added, "if we deliver on all this, it doesn't matter who they nominate — we win."

The Texas senator accused members of Trump's administration of secretly working for the left by undermining the GOP agenda with infighting.

He also told assembled media that friction between the Trump White House and Congress is "profoundly damaging our prospects of success."

Cruz told reporters that he thinks Warren is the Democrats' most likely choice to challenge Trump in 2020, saying he thinks it is "likely" that she decides to run.
