Sen. Rand Paul testified Wednesday in support of a state constitutional amendment restoring voting rights for felons in Kentucky.

The amendment, which passed the Kentucky state Senate by a vote of 34-4, would return the voting franchise to felons after a five-year waiting period, according to the Lexington Herald-Leader.

"When you look at who is being deprived of voting, they are disproportionately people of color," Paul told a legislative committee. "I've become aware of the problem ... not just in regard to voting, but also in terms of getting work," he told CNN in an interview before his testimony.

Paul, who tweeted Wednesday that "the right to vote is a sacred one," also supports the restoration of voting rights for felons at the national level.
