Sen. Ted Cruz's presidential campaign is getting some help from the Bush family.

Neil Bush, the brother of former Florida governor Jeb Bush, who dropped out of the presidential race last month, has joined Cruz's finance team.

Neil Bush's decision to join Cruz's team makes him the first Bush to join a presidential campaign after Jeb Bush's departure from the race.

“We are seeing incredible momentum around our campaign,” Cruz said in a statement. “I am thrilled to welcome these new members to our outstanding team. This race is winnowing down between two candidates, and this is further testament that conservatives are continuing to unite behind this campaign.”

Cruz's campaign announced Tuesday that it has raised $70 million since its inception last March. Cruz has a mix of large and small-dollar donors that other candidates haven't been able to replicate during this election cycle — the campaign said Cruz's average donation is $61.

The campaign said it has raised $1.5 million since Saturday, when Cruz won caucuses in Maine and Kansas.
