Since taking office, Trump has spoken with Arizona state Treasurer Jeff DeWit, a top official on his 2016 campaign, on at least two occasions, according to two sources familiar with the talks. More recently, since June, White House officials have also had discussions with former state Sen. Kelli Ward, who has announced her bid, and former Arizona GOP Chairman Robert Graham, who like DeWit is exploring a campaign.

At a Republican National Committee meeting outside of San Diego in May, David Bossie, Trump’s deputy campaign manager and the president of the influential conservative outside group Citizens United, told Graham that either he or DeWit would likely get substantial backing from conservatives should either enter the contest, according to three people familiar with the conversation.

“Maybe [Flake] should get back on the Trump team. A lot of people believe in Trump’s policies, said former Maricopa County Sheriff Joe Arpaio, a prominent immigration hard-liner who backed Trump, noting that the president remained popular in Arizona. “There’s a silent majority that’s still there, and still in this state, so watch out.”
