Four Republican senators have introduced a constitutional amendment to limit senators to no more than two six-year terms in office, and representatives no more than three two-year terms. To become law, the amendment must be approved by two-thirds majorities of both the Senate and House, and by three-fourths of the states.

Senators Jim DeMint, South Carolina, Tom Coburn, Oklahoma, Kay Bailey Hutchinson, Texas, and Sam Brownback, Kansas, are the co-sponsors.
