John Cornyn withdrew from consideration to be the next FBI director on Tuesday, saying the "best way I can serve is continuing to fight for a conservative agenda in the U.S. Senate."
"Now more than ever the country needs a well-credentialed, independent FBI director," he said in a statement. "I’ve informed the administration that I’m committed to helping them find such an individual."
Cornyn was in serious contention to replace ousted FBI director James Comey, setting off a scramble and speculation around the state over who might succeed him in the U.S. Senate.
Cornyn's announcement came a day after the Washington Post and other media outlets reported that President Donald Trump had disclosed classified information in a recent meeting with Russian officials.
When asked by reporters Tuesday afternoon if the information revealed in the Post report led Cornyn to his decision, he said "no."
At first blush, it appeared Cornyn could be an easy bet for Senate confirmation. He is a popular senator who is well-liked among Republicans and less of a lightning rod to Democrats.
But the rancor in Washington since the dramatic Comey firing escalated over the last week, to the point that even a congenial figure like Cornyn was considered problematic because he is a partisan Republican. Day by day, most Democrats and at least one Republican senator called for a less political appointee.
Trump's firing of Comey last week set off a firestorm, particularly after Trump confirmed suspicions that the FBI's investigation into his campaign's ties to Russia played a part in his decision.
In the Senate, Cornyn will remain majority whip. And ambitious Texas Republicans will have to wait a while for another shot at the U.S. Senate. U.S. Sen. Ted Cruz is up for re-election in 2018, but there is little chatter of a strong primary challenger at this point. Cornyn is up for re-election in 2020.
