Paul Ryan endorses Trump

Republican House Speaker Paul Ryan, cringing from the decision for days after it became clear who would win the party's nomination, has finally endorsed Donald Trump's bid to become U.S. President.

The Wisconsin Republican has voice reservations over Trump's tone throughout the campaign and disagrees with him on many policy areas. Last month, he met with the likely GOP nominee and still withheld his endorsement. As recent as last week, he was still holding out.

But on Thursday he finally acquiesced. In a column in the Janesville Gazette, the Speaker wrote that the two "have more common ground than disagreement." And despite never using the word "endorse" in the article, Ryan's spokesman confirmed it was an official endorsement.

For Republicans, obedience or oblivion.
