PolitiFact editors and reporters will fact-check President Barack Obama's State of the Union address tonight, as well as the responses and reactions.

That includes U.S. Sen. Marco Rubio's rebuttal for the GOP, which will start after Obama's address.

Follow our play-by-play coverage on Twitter (@PolitiFact) or take part in the discussion with our readers on Facebook. Send us your suggestions for fact-checks on Twitter with #PolitiFactThis.

We've written two stories advancing the action.

The first explores whether Obama can take credit for a (slowly) recovering economy. The second reviews Rubio's record on the Truth-O-Meter over 46 fact-checks.

Obama's speech starts at 9 p.m. Join us!
