The Republican Governors Association raised a healthy $6 million in January, the organization announced Tuesday. The haul came during a troubled period for the  RGA chairman, New Jersey Gov. Chris Christie (R), who has come under intense scrutiny over a traffic scandal involving former aides.

The $6 million haul is more than twice as much as as the RGA has raised during the same month in the history of the group, RGA spokeswoman Gail Gitcho said.

Christie took the reins of the RGA late last year, following a decisive reeelction victory. But his political momentum has been blunted by a scandal involving top aides and appointees who snarled traffic in Fort Lee in an apparent act of political retribution.

Republicans are defending 22 gubernatorial seats this cycle, compared to Democrats' 14.

Christie raised $1.5 million last week during a swing through Texas, the RGA said.
