Quick Summary

Senator Thom Tillis criticized former President Donald Trump for supporting Ken Paxton over incumbent John Cornyn in the Texas Senate Republican primary. During an interview on CNN’s State of the Union, Tillis called Trump's decision a "colossal mistake" that could put the Senate seat at risk for Republicans. The race has implications for November’s midterm elections as Paxton now faces Democratic candidate James Talarico, who if elected would be the first Democrat to win statewide office in Texas since more than 30 years ago. Tillis emphasized that Trump's endorsement of Paxton over Cornyn was an "unforced error" and highlighted Cornyn's strong record compared to Paxton’s series of political scandals.

Story summary

US Senator Thom Tillis, a frequent critic of President Donald Trump, criticized the president's decision to support Ken Paxton over incumbent John Cornyn in the Texas Senate Republican primary. This endorsement took place just days before Paxton defeated Cornyn, advancing to face Democratic candidate James Talarico in the general election on November 3rd. Tillis argued that Trump's move was a "colossal mistake" and described it as an "unforced error," suggesting it has put the Senate seat at risk for the GOP. The race had significant implications for Trump’s strength heading into November’s midterm federal elections, with Cornyn's defeat allowing Democrats to potentially exploit Paxton's long-standing scandals in their campaign efforts.
