Former Florida Gov. Jeb Bush (R) endorsed New York congressional candidate Chris Cox Wednesday. Cox is locked in a Republican primary in New York’s 1st Congressional District. 

Cox, who is largely self-funding his bid, is the son of New York GOP Chairman Ed Cox and the grandson of former President Richard Nixon.

“Chris is a leader with fresh ideas, a dedication to government accountability, and a commitment to serving the best interests of his constituents,” Bush said in a statement. “The challenges we face as a country present us with an incredible opportunity to advance bold and lasting reform that will build a stronger America for the future. I believe Chris will bring creative, conservative and common-sense solutions to tackle the big issues of our day.”

Cox has been under fire from some New York Republicans to withdraw from the race, and last month his top-tier consulting team, made up almost entirely of John McCain presidential hands, up and quit. Fred Davis, Mark Salter and Josh Geleris were among those who left, citing strategic differences with the campaign. 

Cox was the New York state chair of McCain’s 2008 presidential campaign. 

He faces Randy Altschuler and George Demos in the Republican primary for the seat held by Rep. Tim Bishop (D).
