NextGen America is going negative in a House race in Pennsylvania, less than one week before the Democratic primary. The group is backed by billionaire Democrat Tom Steyer and focused on mobilizing young voters.

The digital ads launched Wednesday target North Hampton County District Attorney John Morganelli, who is running in a competitive Democratic primary in Pennsylvania’s 7th District. It’s the group’s first action in a primary in the 2018 cycle, and the first time since 2013 that the group has launched negative ads in a Democratic primary.

Morganelli is considered a top candidate in the race due to his high name recognition, but the group has taken issue with his anti-abortion rights and anti-illegal immigration stances.

Morganelli is a staunch opponent of so-called sanctuary cities that do not enforce federal immigration laws. Morganelli also appealed to then-President-elect Donald Trump on Twitter saying he hoped to serve the administration.

“John Morganelli does not support a women’s right to choose and has repeatedly sought to make lives harder for immigrants,” NextGen America spokeswoman Aleigha Cavalier said in a statement.
