AMERICA FIRST POLICIES, the pro-Trump/Pence outside group that Pence has been raising for, is preparing a seven-figure ad buy against HELLER — Maggie Haberman (@maggieNYT) June 23, 2017

The group was formed by six former members of Trump and Pence's staffs, including former spokeswoman Katrina Pierson and former deputy campaign manager Rick Gates. The group formed in January to gather people who "believe in the Trump agenda," Gates said at the time.

“This goes beyond Trump supporters,” Gates told the Associated Press in January. “We’re trying to capture all people who believe in the Trump agenda.”

Heller announced Friday that he would not support the Senate bill in its current form. Heller, who is the fifth GOP senator to defect, says that it will be "difficult" to win over his vote.

"I’m announcing today that in this form I will not support it," Heller said Friday during a press conference.

"It’s going to be very difficult to get me to a yes," Heller continued. "You have to protect Medicaid expansion states. That’s what I want."
