Senior Republican advisers backing anti-establishment firebrand Roy Moore have deep ties to former Florida Gov. Jeb Bush and posted tweets critical of President Trump during the 2016 campaign.

Brett Doster, Moore’s campaign manager in a closely watched Alabama Senate race, ran Bush’s South Carolina operation in last year’s GOP presidential primary. Mike Hanna, consulting for a pro-Moore super PAC, has been in Bush’s inner circle since the Floridian’s 1994 gubernatorial campaign.
