Pennsylvania's Democratic U.S. Rep. Allyson Schwartz says she won't cut ties with a centrist think thank that criticized high-profile Democrats.

Schwartz is a candidate for Pennsylvania governor. She told The Associated Press on Friday she'll remain on the advisory board for the Third Way organization "for now."

But she says the group was wrong to last week publish an opinion article that included "unnecessarily harsh and divisive" criticism of liberal favorites Massachusetts U.S. Sen. Elizabeth Warren and New York City Mayor-elect Bill de Blasio.

The Third Way authors described Warren's plans to expand Social Security benefits and delay Medicare reforms as fantasy.

Prominent liberals called on Schwartz and other Democrats to end their affiliations with the group.

Friday's comments were Schwartz's first on the issue.
