The Progressive Change Campaign Committee (PCCC) is going up with new ads targeting two key GOP swing votes following a sexual assault allegation against Supreme Court nominee Brett Kavanaugh.

"If Susan Collins and Lisa Murkowski don’t publicly oppose Kavanaugh, their legacy will be putting someone into the Supreme Court as the deciding vote who is hostile to women on all levels. There is too much at stake to allow someone who is a danger to women to serve a lifetime appointment to the Supreme Court," said Stephanie Taylor, PCCC co-founder.

ADVERTISEMENT She added that "we believe Dr. Christine Blasey Ford, and we respect her bravery to come forward publicly with her horrific experience. Brett Kavanaugh is unfit to serve on the Supreme Court."

The ads will initially run in the Bangor Daily News and the Ketchikan Daily News on Thursday. PCCC is planning to extend and expand the run of the ads based on grass-roots funding.

"Senator Collins— do you believe Dr. Christine Blasey Ford? And do you believe Trump and Kavanaugh when they express hostility to Roe, saying it is not settled law?" the Maine ad asks, referring to Roe v. Wade, the 1973 Supreme Court case that legalized abortion nationwide and urging constituents to call Collins and tell her to vote "no."

The Alaska version of the ad asks Murkowski the same question.

Neither Collins nor Murkowski have said how they will vote on Kavanaugh and are not expected to announce their decision before a high-stakes Senate Judiciary Committee hearing scheduled for Monday. Both Kavanaugh and Ford have been invited to testify.

The hearing was scheduled after Ford spoke publicly about her allegation against Kavanaugh to The Washington Post, saying he pinned her down to a bed, groped her and tried to remove her clothes during a party when they were both in high school.

Kavanaugh has denied wrongdoing.

But outside groups are stepping up their efforts to sway a small group of swing-vote senators. Republicans hold a 51-49 majority, meaning they could only afford to lose one senator without needing help from Democrats to confirm Kavanaugh.

Planned Parenthood Action Fund, Know Your IX, United State of Women and End Rape On Campus on Tuesday launched a multistate effort to hold events ahead of Monday's hearing. Sexual assault survivors and advocates will use the events to try to share their stories with senators and urge them to oppose Kavanaugh.
