Sen. Mazie Hirono (D-HI) on Monday criticized Republicans for characterizing the sexual assault accusations against Brett Kavanaugh as politically motivated.

A Yale University classmate of Kavanaugh, Debbie Ramirez, claimed in a New Yorker article that the Supreme Court nominee exposed himself to her at a college party.

The alleged incident occurred about 35 years ago, similar to the accusation by California professor Christine Blasey Ford, who has claimed that Kavanaugh sexually assaulted her at a high school party.

"Rather than dealing with trying to get to the facts of the allegations, no. [Republicans] just would rather characterize this as being totally politically motivated," Hirono said to reporters on Capitol Hill.

Kavanaugh has firmly denied both allegations against him, as Senate Democrats have called for his confirmation to the high court be delayed.

He and Ford are expected to testify on Thursday about the allegations before the Senate Judiciary Committee.

Kavanaugh called Ramirez's claim a "smear, plain and simple."

Hirono added on Monday that if any group is being politically motivated, it's the GOP.

"[They] are stonewalling an investigation that would and should occur otherwise."
