The following American politicians were affiliated with the Tea Party movement, which was generally considered to be conservative, libertarian-leaning, and populist. The Tea Party movement advocated for reducing the U.S. national debt and federal budget deficit by reducing federal government spending and taxes. It was not a single, formal political party, but rather represented by activist groups such as the Tea Party Patriots and the Tea Party Express. The Tea Party Caucus was the primary grouping of Tea Party representatives and senators in Congress and was described as having a voting record similar to a third party.
