The American Bar Association is calling on the Senate Judiciary Committee to pause the nomination process for Trump Supreme Court nominee Judge Brett Kavanaugh until an FBI investigation is conducted to investigate the multiple allegations of sexual assault against him.

So far, the FBI has not been instructed to investigate, an order that would have to come from the White House.

Kavanaugh and accuser Dr. Christine Blasey Ford testified before the committee yesterday, where she again said she was in favor of an FBI investigation into the alleged incident of sexual assault when the two were in high school.

Despite having given the nominee its highest rating of a unanimous "well-qualified" for the Supreme Court, in a letter sent to Sens. Chuck Grassley and Dianne Feinstein and obtained by CNN, the legal group said that "because of the ABA's respect for the rule of law and due process under law" the nomination process should be halted and an investigation completed. It is signed by the organization's president, Robert Carlson.

"Each appointment to our nation's Highest Court (as with all others) is simply too important to rush to a vote," he wrote. "Deciding to proceed without conducting additional investigation would not only have a lasting impact on the Senate's reputation, but it will also negatively affect the great trust necessary for the American people to have in the Supreme Court."

Abuse survivors have come out in support of Dr. Ford, and have called for an FBI investigation, alongside Democrats. Republican lawmakers have brushed aside those calls and are holding a hearing today in the Senate Judiciary Committee on Kavanaugh's nomination, which, if successful, will be sent to the full Senate for a vote this weekend.

LGBTQ groups are also concerned that Kavanaugh would vote against the community's rights, especially after he failed to answer a question about gay marriage. Women's rights advocates are also concerned that he could vote against Roe v. Wade.

"The ABA is an outside organization, like any other that can send us letters and share their advice, but we're not going to let them dictate our committee's business," Grassley said during today's hearing.
