Vitter praised Obama’s decision not to attend a bilateral summit being hosted by Putin ahead of the G-20 summit. The administration said it made the decision after a lack of progress on numerous issues between the two countries and Moscow's decision to grant National Security Agency leaker Edward Snowden temporary asylum.
Vitter has criticized Obama for calling for a reduction to the U.S. nuclear arsenal, saying it weakens the nation's military. Putin and Obama were expected to discuss missile defense and arms control at the summit. Both countries have agreed to eliminate some of their nuclear weapons, but Obama has called for even further reductions.
Vitter has said the administration should seek Congressional approval before making additional cuts to the nuclear weapons stockpile.
