Sen. John McCain (R-Ariz.) on Tuesday applauded President Barack Obama's decision to send 1,200 National Guard troops to the U.S.-Mexico border but said even more are needed.

McCain this year called for 3,000 National Guardsmen and additional 3,000 Border Security officers to be sent to protect against an uptick in violence and drug cartel activity there. 

He tweeted:

1,200 Nat'l Guard is a first step, but it's not enough. I've been calling for the Guard to secure our SW border for years - we need 6,000!
