Frankfort, Ky. (AP) - Sen. Rand Paul has already filed to seek re-election to the U.S. Senate in 2016.
The Kentucky Republican who has been talking about possibly running for president next year filed a statement of candidacy to run for a second term in the Senate on March 21, some three months after taking office.
Paul, the son of Texas congressman and former Republican presidential candidate Ron Paul, won the GOP primary in Kentucky last year over a Republican establishment candidate and followed that up with a general election win over an establishment Democrat.
Rand Paul has suggested he may run for the Republican presidential nomination next year if his father doesn't. While his father hasn't officially announced another presidential run, he has been testing the water.
