Sen. John Cornyn, R-Texas, argued Thursday that Joe Lieberman is "probably the only person" who could get 100 votes in the Senate for FBI director.

Cornyn, who is the majority whip in charge of rallying members of his party behind certain votes, was once considered a candidate for the job after President Trump fired FBI Director James Comey last Tuesday.

Cornyn pulled his name from consideration due to mounting opposition against Trump picking a GOP politician.

Lieberman, a former senator from Connecticut who was Al Gore's running mate in 2000, is a top candidate for the position, Trump confirmed Thursday. He would not need 100 votes to be confirmed, only a simple 51-vote majority under current Senate rules. But a 100-vote confirmation would provide a reassuring air of confidence in the person to replace Comey, who was no stranger to controversy.

Cornyn's support of Lieberman echoes that of several of his Republican colleagues Thursday. Sen. John McCain, R-Ariz., said "Joe Lieberman has more experience than all of my [Democratic] colleagues combined." Sen. Lindsey Graham, R-S.C., a close friend of McCain's, told reporters that Lieberman would be a "good choice" for FBI director.

Meanwhile some Democrats expressed concerns about Lieberman, including Sen. Claire McCaskill, D-Mo., who said she would prefer someone with law enforcement experience to someone who was a politician.

To this line of criticism from Democrats, McCain had a blunt retort: "screw them."
