Despite facing a serious battle to hold on to her seat in the red state of North Dakota, Democratic Sen. Heidi Heitkamp will vote "no" on Supreme Court nominee Brett Kavanaugh.
The senator told WDAY of her decision on Thursday, ahead of a possible vote this weekend.
She said she believed the testimony of Dr. Christine Blasey Ford, who alleges Kavanaugh tried to sexually assault her when they were high schoolers in the '80s.
"The one thing that I learned from that experience was really the most important thing you can tell a victim, is that you believe them.
"I believe Dr. Ford, I believe her story."
"I think it's critically important that the message is sent to women and girls and people across this country that when you believe a victim, you should say it," she added.
"My belief that Dr. Ford is telling the truth, leads me to the conclusion that I have to vote 'no' on Judge Kavanaugh."
In a longer statement she tweeted, Heitkamp also said the comments made by Kavanaugh at last week's hearing make her question his honesty, temperament and his impartiality.
With the Senate currently at 51-49 in the GOP favor, there would need to be one Republican "no" to stop Kavanaugh joining the Supreme Court.
The decision could well signal Heitkamp's defeat in November's elections, despite having been one of the members of Congress more likely to vote for President Trump's policies during his time in office.
She said this decision wasn't about politics.
