He says the agency's domestic spying violates the constitution

After months of threatening legal action against the Obama administration, Kentucky’s Republican Senator Rand Paul has declared he will officially join a class-action lawsuit against President Obama and several senior administration officials over the National Security Agency’s domestic spying program.

Paul said in a statement that surveillance of American citizens defies the fourth amendment, WFPL news reports. The 2016 presidential prospect will file the suit on Wednesday in Washington, D.C. and address reporters at a press conference.

“I expect this case to go all the way to the Supreme Court and I predict the American people will win,” Paul said in the statement from his political action committee RandPac.

The NSA’s surveillance program gained national attention when government contractor Edward Snowden released classified documents about the program last year. Spying began under Republican President George W. Bush after the 9/11 attacks and continued under Obama.
