Sen. Elizabeth Warren (D-Mass.) called for a delay Tuesday of Judge Neil Gorsuch’s Supreme Court confirmation vote, citing the FBI investigation into potential ties between President Trump’s campaign and Russia.

As the Senate Judiciary Committee continued its hearing on Gorsuch’s confirmation, the Democratic senator sent a flurry of tweets to say the Russian investigation should take priority.  

The FBI Director testified @realDonaldTrump‘s campaign is under investigation for collusion w/ Russia. Lifetime court appointments can wait.

Warren suggested in one tweet that the Republicans are trying to “move on” to Gorsuch, a day FBI Director James Comey testified to the House Intelligence Committee that the FBI is investigating Trump’s campaign and Russia.

 Warren also accused Gorsuch of favoring big businesses in his rulings. 

I’ve strongly opposed the Gorsuch nomination. Giant companies don’t need another Supreme Court justice to tilt the law in their favor.

Warren joins a growing number of prominent Democrats, including House Minority Leader Chuck Schumer (D-N.Y.) and Democratic National Committee Chair Tom Perez, who say the ongoing Kremlin investigation means that Gorsuch’s confirmation vote should be put on hold. 

The committee will likely vote on Gorsuch’s nomination the first week of April before it goes to a full Senate vote.
