Beto O’Rourke met with Senate Minority Leader Chuck Schumer (D-NY) last week to discuss taking on Sen. John Cornyn (R-TX) in 2020, according to a Wednesday Politico report.

Cornyn is seen as vulnerable after O’Rourke’s surprisingly competitive bid against Sen. Ted Cruz (R-TX) in 2018. The senator has already amassed the largest war chest of any of his peers.

“We’ve gotten complacent,” Cornyn told Politico. “The tectonic plates shifted in Texas in 2018 and I think everybody realized we need to do something different and to address those concerns or else we’re in trouble.”

O’Rourke is expected to make a decision on a possible presidential bid by the end of this month.
