As Harvey rages, Texas senators defend votes against Sandy funding

Cruz said the Hurricane Sandy package had “billions in unrelated spending."

Cornyn's press office noted that before his "no" vote, he supported an amendment that would have provided $24 billion in aid, minus what his team called "unrelated spending, which included money for things like repairing fisheries in the Pacific."

However, his staff did not say whether he would seek spending cuts corresponding to Harvey relief funding if Congress votes on the relief after legislators return next week.

He reiterated that position Monday, saying during a cable news appearance from a Houston recovery center that two-thirds of the Sandy bill "had nothing to do with Sandy."

While the 2013 Sandy bill did contain funding for all the things Cruz and Cornyn mentioned, each agency and program pointed to problems created by the storm that warranted the funding.

The fisheries funding cited by Cornyn's office included $5 million "for necessary expenses related to fishery disasters during calendar year 2012 that were declared by the secretary of commerce as a direct result of impacts from Hurricane Sandy," according to the NOAA.

In a statement released Monday, Cruz did not address Congress' likely role in funding Harvey recovery efforts, nor did his press office answer ABC News' questions about whether he would seek cuts to offset any funding allocated.
