Paul is not doing it on behalf of the Republican Party, his press secretary told The Hill. Instead, he is offering his thoughts “as a concerned senator,” she said.
The Tea Party senator has been leading the charge in Congress against Obama’s call for intervening in Syria.
On Monday, Paul circulated a letter to his congressional colleagues urging them not to back it either.
“I will not vote to send my son, your son, or anyone's daughter to fight for stalemate. The President must make the case for war,” he wrote. “Thus far, he and his Administration have tried to make the case for 'skirmish.'”
An increasing number of lawmakers have expressed their intentions to vote against military action.
The White House, however, is reportedly giving Syria a chance to hand over its chemical weapons stockpile after accepting Russia’s proposal Monday.
It’s now unclear whether or when a vote to strike Syria would come before both chambers.
