PolitiFact is a project of the Tampa Bay Times to help you find the truth in American politics. Reporters and editors from the Times fact-check statements by members of Congress, the White House, lobbyists and interest groups and rate them on their Truth-O-Meter:

TRUE – The statement is accurate and there’s nothing significant missing.

MOSTLY TRUE – The statement is accurate but needs clarification or additional information.

HALF TRUE – The statement is partially accurate but leaves out important details or takes things out of context.

MOSTLY FALSE – The statement contains an element of truth but ignores critical facts that would give a different impression.

FALSE – The statement is not accurate.

PANTS ON FIRE – The statement is not accurate and makes a ridiculous claim.

PolitiFact also tracks campaign promises of President Barack Obama and Republicans in Congress. You can track the progress on the Obameter and our GOP Pledge-O-Meter.
