"To be accurate, I voted for $23.8 billion in Sandy funding," Cornyn told reporters while standing next to Sen.

"The reason I voted against the larger bill is because it included other things that weren't Sandy superstorm-related."

Hurricane Harvey slammed into Texas last Friday, bringing record rainfall that has caused extensive flooding and billions of dollars in damage to properties in the populous Houston metropolitan area. 

The Texas lawmakers were two of the 36 senators who voted against the final federal relief package in 2013 for Sandy recovery efforts. Cornyn has defended his decision in the past, arguing it was based on "unrelated" appropriations included in the bill. 

"It's important to remember that these supplemental appropriations for these emergencies are an exception," Cornyn told reporters Tuesday when asked if the lawmakers would work to make sure that Harvey relief came in the form of a "clean" funding bill.

"It's not the standard way the Congress appropriates money, and there was always an opportunity to come back behind that after that money was depleted to do more. So that's the thought here," Cornyn said.
