Tennessee Republican Sen. Lamar Alexander's website included a link to his campaign's Facebook account, a violation of Senate rules. Senate rules say "the placement of logos or links used for personal, promotional, commercial, or partisan political/campaign purposes is prohibited."

BuzzFeed made an inquiry with the Senate rules committee about the specific violation, shortly after which the Senator's website was changed to link to his non-campaign Senate Facebook.

A spokesman for Senator Alexander said, "A recently updated link inadvertently directed website visitors to a non-official Facebook page rather than an official Facebook page. When it was discovered that the link was tied to the wrong site, it was corrected."
