Biden campaign continues focus on abortion with new ad buy, Kamala Harris campaign stop in Philadelphia

President Biden's campaign is launching a new seven-figure ad buy Thursday centered around abortion, a centerpiece issue for his campaign, as it attempts to link restrictive state abortion bans to former President Donald Trump. 

It will run on the two-year anniversary of the leak of a Supreme Court draft opinion on the Dobbs case, which overturned Roe v. Wade and transferred decisions about abortion access to the states. 

The campaign ad, titled "Prosecute," first shared with CBS News, features an OBGYN physician in Texas talking about how the state's near-total abortion ban, enacted after the Dobbs decision, forced her to flee the state to get care.
