Priorities USA, the main outside group supporting the Democratic presidential nominee, has been hammering Trump, the Republican presidential nominee, through a TV campaign in battleground states that should far exceed $100 million by November. It raised $12 million in June.

The group has also put more than $35 million into digital advertising, a significant and growing amount of which is aimed at motivating Hispanic voters — a group that overwhelmingly opposes Trump.

In a statement released Saturday, Justin Barasky, Priorities USA's communications director, said the group had now banked $110 million in donations and secured an additional $44 million in "commitments" from its donors.

Some of the super-PAC's biggest donors include hedge fund billionaire George Soros and California-based entertainment mogul Haim Saban.

Priorities USA finished July with $38.7 million on hand — money that will be used to continue the group's strategy of portraying Trump as temperamentally unfit to be president and hammering the GOP nominee over his rhetoric about women, minorities and people with disabilities.
