Story highlights The leader of the 'Draft Biden' effort is forming an anti-Donald Trump super PAC

The group is meant to appeal in part to those who aren't enamored of Hillary Clinton

(CNN) A new super PAC is forming with a top priority of stopping Donald Trump, not promoting Hillary Clinton.

The group, called Keep America Great, is intended to cast a wide net of donors and supporters, CNN has learned. It is designed to attract admirers of Bernie Sanders and disaffected Republicans who may be uneasy about being aligned with a specifically pro-Clinton organization.

Jon Cooper, who was a leader in the unsuccessful effort to draft Vice President Joe Biden into the White House race, will be the chairman of Keep America Great. The group, which pledges to run television ads and a digital campaign, will be announced Thursday.

"Our mission over the next five months is to help ensure that everyone is aware of Mr. Trump's long record of distortions, lies and even fraud," Cooper said. "His recent racist attacks against a respected federal judge, his fervent support of assault weapons even after the mass murder in Orlando, his mocking of people with disabilities -- these all provide a window into his heart and soul. And that should give all fair-minded Americans pause."

While several groups have been formed to stop Trump, Keep America Great is intended to appeal to those who may have misgivings about Clinton or who are not eager to be associated with the Clinton campaign.
