Critics claim the organization wasn't transparent about where past disaster relief money went.
A 2015 report from NPR and ProPublica did say the Red Cross raised more money than other nonprofits for the 2010 Haiti earthquake.
But that report also claimed Red Cross' on-the-ground efforts were pretty minimal for what was promised. For example, the Red Cross built only six homes, far fewer than the organization said it would.
The Red Cross president said although only six homes were built, the organization made other investments to offer people housing.
Another issue in Haiti that critics now cite is an investigation from Iowa Sen. Chuck Grassley. That investigation found the organization put more of the money it raised in Haiti toward overhead than claimed.
The president of the Red Cross argued 90 percent of funds did go toward Haiti, as pledged.
Still, a charity watchdog flagged the Red Cross' financials in the past two years. Charity Navigator lowered its score of Red Cross' transparency.
The organization hasn't yet released how much it's gotten so far and how much it plans to put into certain areas for Harvey.
Of course, this doesn't mean you shouldn't donate to Hurricane Harvey disaster relief. The Federal Emergency Management Agency lists the best practices for donating and volunteering as well as examples of local organizations to give to.
