Sen. Ted Cruz (R-Texas) slammed the policy of sanctuary cities tonight, stating that "the Democratic Party supports illegal immigration." 

The 2016 GOP presidential candidate said that sanctuary cities have been a "persistent problem" in Texas. 

He said that the Democratic mayors who are elected in his state decline to enforce the law. 

"It varies in terms of how brazen it is, it's not always as brazen as San Francisco is," he explained. "But it's a problem when you have cities that are in the control of the Democrats and don't want to follow the law."

Cruz said that some law enforcement officers and city officials won't cooperate with federal immigration laws and have created sanctuary cities. 

"It's because the Democratic Party supports illegal immigration," he stated. "They don't even call it illegal immigration. They've come up with this 'undocumented' term."

He added that Democrats are "endangering the security" of America because they refuse to follow the law.
