Senator Joni Ernst, R-Iowa, said that she will continue to support Judge Brett Kavanaugh's nomination to the Supreme Court should the FBI not find additional evidence or corroboration of accuser Christine Blasey Ford's allegations of sexual assault. Ernst told "CBS This Morning" Tuesday that based off of Ford's testimony before the Senate Judiciary Committee, the "corroboration wasn't there" with the "witnesses she brought forward."

"What we want to see is, is there evidence or corroboration that the FBI is able to find through the supplemental investigation that would corroborate Dr. Ford's accusations and if not, I will continue to support Judge Kavanaugh based on the information that I have at this time," Ernst said.

Asked what a vote of support for Kavanaugh sends to women, particularly from a female senator, Ernst said her positive vote shows women that "we are innocent until proven guilty."

"I have absolutely no doubt after reviewing Dr. Ford's testimony that she has suffered from something very traumatic in her lifetime, but simply the corroboration wasn't there with even the witnesses that she brought forward," Ernst said.
