At least three House lawmakers will miss this evening's series of votes on landmark climate change legislation.

Three members -- two Democrats and one Republican -- have confirmed they will miss the vote this evening, scheduled to begin at 5 p.m.

Rep. Jeff FlakeJeff FlakeLawmakers reintroduce measure to lift Cuba travel restrictions Majority of Senate supports Cuban tourism bill Montana GOP senator: Gianforte 'needs to apologize' MORE (R-Ariz.) will miss the vote due to a family conflict, Rep. Patrick Kennedy (D-R.I.) is in rehab seeking treatment for alcoholism, and Rep. Alcee Hastings (D-Fla.) is in Albania.

Since that will bring the total number of voting lawmakers for today down to at least 432, House Democrats will need 217 votes to pass the climate change bill.

A rules vote passed by a 217-205 vote earlier today, a vote which 11 lawmakers missed. Rep. John Lewis's (D-Ga.) office told The Hill he will vote, while a call to Rep. John Sullivan's (R-Okla.) office was not immediately returned. Sullivan is also seeking treatment for alcoholism.
