Liberal filmmaker Michael Moore took to Twitter to offer President Barack Obama a mixed bag of congratulations for his Nobel Peace Prize awarded earlier today.

The Nobel Committee surprisingly gave Obama the award; he was in office only two weeks before the deadline for the 2009 prize.

Moore tweeted:

Congratulations President Obama on winning the Nobel Peace Prize! You have filled the world with hope -- now you must make peace happen.

Upon awarding Obama the prize, the committee cited Obama's "extraordinary efforts to strengthen international diplomacy and cooperation between peoples."

Obama becomes only the third sitting president to earn the peace prize; Theodore Roosevelt won in 1906 and Woodrow Wilson won in 1911.
