A Republican super PAC named The Lincoln Project that has been critical of President Trump, announced that they saw their biggest single-day fundraising total after the president repeatedly slammed the group on Twitter earlier in the week.

Reed Galen, an advisory committee member of the Lincoln Project’s told the press that the group raised $1 million in a single day after Trump’s tweets, which targeted the group over its anti-Trump advertisement titled “Mourning in America.”  

“A group of RINO [Republicans In Name Only] Republicans who failed badly 12 years ago, then again 8 years ago, and then got BADLY beaten by me, a political first-timer, 4 years ago, have copied (no imagination) the concept of an ad from Ronald Reagan, ‘Morning in America,’” Trump tweeted early Tuesday.

In another tweet, he took aim at several individual operatives associated with the super PAC, like Republican strategists Rick Wilson and Steve Schmidt, and especially George Conway, a frequent critic of the president and also the husband of White House counselor Kellyanne Conway. 

Galen also said in an interview that the ad has been airing on cable markets in the D.C., region since Tuesday and will begin airing in swing states next week. The group also aired an advertisement in support of Joe Biden in Wisconsin and Michigan in recent weeks.

The group announced on Wednesday that it will run ads against certain Trump allies currently serving in the Senate.

“Thanks to Trump, we’ll keep ‘Mourning in America’ running longer, then get back to our regular programming, which will include more assaults on Trump’s record and going after some of his most ardent enablers in the Senate,” John Weaver, another co-founding member of the group, told the press. He chose not to specify which senator or senators the ads would be taking aim at.
