A fund for the victims of the Pulse nightclub shooting in Orlando has more than $26 million in donations.

Orlando officials said Monday that money from the OneOrlando Fund will start being distributed by the end of the month to the victims of the massacre at the gay nightclub.

Officials say 351 claim forms have been submitted. They say some of them are competing submissions for dead victims.

During a meeting with survivors and families last month, Ken Feinberg, the head administrator of the fund, had warned that squabbling over estate questions could be the biggest obstacle to the distribution of the money.

Gunman Omar Mateen opened fire at the Pulse nightclub June 12 in a rampage that left 49 victims dead and 53 wounded, making it the worst mass shooting in modern U.S. history.
