Republican Rand Paul is introducing an amendment to the Senate immigration reform bill that would bar undocumented immigrants from voting in federal elections until they obtain U.S. citizenship.

The proposed is being put out on the same day the Supreme Court struck down an Arizona law that required residents to prove their citizenship before voting.

Paul's "Secure the Vote" amendment is aimed a tackling voter fraud and ensures those on work visas or given status under the Senate bill are not allowed to vote in federal elections until they become citizens.

The amendment would also provide states with new procedures to check that those individuals are not illegally registered to vote.

"Not only would this amendment prevent voter fraud, it would also clear up the problem created by today’s Supreme Court decision," Paul said in a statement. "My amendment requires states to check citizenship before registering people to vote in federal elections."

Former Kentucky Secretary of State Trey Grayson says Senate Republican Leader Mitch McConnell will likely have a primary battle, but questions if that candidate will provide a viable challenge.

In an interview with Politico this week, McConnell acknowledged he might have a GOP opponent but boasted "there is not any chance" he could lose such a race.

Tea Party leaders in the state have promised a challenger is forthcoming who will take on McConnell's positions from a more conservative viewpoint, but no one has stepped up at this time.

Grayson was a McConnell protégé who lost to Rand Paul in the 2010 Republican primary.

He says McConnell has done a good job of keeping the state GOP unified and made solid partnerships with libertarian and tea party leaning lawmakers.

"I think the question is there going to be somebody out there who can give him a real run for the money, and it doesn’t look like it. There’s certainly a group of folks—some tea party leaders and others, David Adams for example—who are trying to find a candidate who can take him on. And everyday that candidate’s not in the race it becomes that much harder of a proposition," he says.

In a blistering statement, U.S. Senator Rand Paul, R-Ky., says President Obama has "sunk to a new low" after reports the National Security Agency has collected millions of U.S. citizen's telephone records.

A story in The Guardian revealed the practice and shows a court order requiring Verizon to provide the NSA with information about calls in its system on an "ongoing, daily basis" from inside county as well as between U.S. customers and people in foreign countries.

The White House is defending the practice as a tool to combat terrorism, but civil liberties advocates say the practice is similar to NSA overreach under President George W. Bush in 2006.

Paul says the president is abusing his executive power, but that the Democratic-controlled Senate failed to put Fourth Amendment protections in the post-9/11 surveillance laws.

From Paul's office:

The National Security Agency's seizure and surveillance of virtually all of Verizon's phone customers is an astounding assault on the Constitution. After revelations that the Internal Revenue Service targeted political dissidents and the Department of Justice seized reporters' phone records, it would appear that this administration has now sunk to a new low.

Progressive Change Campaign Committee has launched a new ad criticizing Senate Republican Leader Mitch McConnell over proposed gun control measures.

This is the second spot by the group to target McConnell, and like the previous ad it features a Kentucky gun owner and military veteran who supports a ban on assault weapons.
