Sen. Ted Cruz, R-Texas, on Wednesday accused New Jersey Gov. Chris Christie of being "desperate" to get in the news, and said that's why he's been attacking Cruz in the press this week.

"I'm sorry that there are politicians who seem really desperate to get their names in the news and are really saying whatever they need to do that," Cruz told Fox News. "We have a crisis on the ground of people who are hurting right now, people who are in harm's way, whose lives and families are in jeopardy as we speak."

Christie made the TV rounds Tuesday and Wednesday to talk about his experience with Hurricane Sandy and the need for Congress to swiftly approve federal assistance for the communities affected by Hurricane Harvey, which hit southeastern Texas over the weekend. He criticized Cruz on Tuesday for attempting to "exploit" the 2012 hurricane for political gain, by opposing an aid package for those impacted by Sandy.

Cruz defended his position by saying the Sandy bill included funding for a number of extraneous items.

"For folks who are focused on raising political shots and snipes about the Sandy bill, facts matter, and a simple fact is that Sandy bill was over $50 billion, and 70 percent of it was nonemergency," Cruz said Wednesday. "Only 30 percent of the funding was emergency funding for the victims of Sandy."

The Texas senator also said he was hopeful that Congress would unite to pass a bill providing aid to Texans affected by Hurricane Harvey and the devastating flooding the storm brought with it.

"Congress will step up in a serious way to meet what is going to be an enormous need," he said. "The damage has been devastating. No one right now has calculated the magnitude of the damage because everyone is rightly focused on saving lives."

Christie on Wednesday dismissed Cruz's claim that most of the Sandy bill was for nonemergency purposes.

Parts of southeastern Texas have been hit with catastrophic flooding in the last few days, as record rainfall drenched that area of the state.

Thousands of people have been displaced from their homes as water levels have continued to rise.

Officials with the Federal Emergency Management Agency said Wednesday nearly 200,000 people have asked for assistance, and the agency expects that number to increase.
