'There are no rules right now': South Carolina Congresswoman brought her dog to historic multiday House Speaker vote

• Rep. Nancy Mace brought her dog, Libby, to work on the third day of House Speaker voting.
• She was photographed casting her vote with Libby in-hand on Thursday.

Rep. Nancy Mace's dog, Libby, was among those in attendance to witness one of the most chaotic elections for speaker of the House in more than a century.

Ahead of Rep.-elect Kevin McCarthy's election as next speaker of the House on Saturday morning, Libby visited the House Chamber on the third unsuccessful day of voting on Thursday.

Mace, a South Carolina Representative, cast her vote to adjourn with one hand while holding her dog in the other. She was also seen holding Libby on the House floor as discussions dragged on in Washington, DC.

Earlier on Thursday, the lawmaker shared a video of Libby running around her office, with the caption "Day 3 vibes."

"The feeling is mutual Libby #RunningToTheFloor," Mace wrote in the video.

When asked if dogs were allowed on the House floor, Mace replied "there are no rules right now," The Independent reported.

Libby made yet another appearance on the fourth day of voting, seen slumped on a couch in the Longworth House Office Building on Friday alongside the caption "Day 4 vibes."

The video of Libby zipping around the office captured the chaotic nature of the House's heated discussions over who would take over as the next leader.

After a total of 15 ballots spanning five days, McCarthy was elected Saturday in what became the longest speaker selection in over a century, Insider reported. The lengthy voting period was the result of in-fighting and division among Republicans, who currently hold a slim majority in the House.

"That was easy, huh?" McCarthy joked, after winning the election after 1 a.m. Eastern Time on Saturday. "My father always told me it isn't how you start, it is how you finish, and now we need to finish strong for the American people."
