The other major Cruz donor was Robert Mercer, a New York hedge-fund manager who gave $13.5 million to his own related pro-Cruz group, Keep the Promise I, which focused on TV advertising.
"It's too early to discuss whether we will put any more money into the presidential race," Kellyanne Conway, the group's president, said in an interview. Nevertheless, she hinted that "there's a big difference between anti-Hillary and pro-Trump" messages.
Mercer's daughter and political adviser, Rebekah, recently co-produced a documentary bashing Hillary Clinton that is scheduled to premiere in the U.S. during the week of the Democratic convention in July. (The movie wasn't funded by the PAC.)
Conway said the group does plan to get involved in congressional races, although it hasn't identified which ones yet. "There are many limited-government, free-market candidates who have not yet received the full funding they will need in the fall," she said.
