Wyoming Governor Matt Mead has joined a majority of U.S. governors in saying he doesn't want to accept Syrian refugees.

In a letter to President Obama the governor says Wyoming ''will not accept a system that allows terrorists from any country in our state".

He says before any more Syrian refugees are allowed in the President needs to make sure a proper vetting system is in place to make sure terrorists aren't among those seeking refuge in the U.S.

The governor issued the letter on Tuesday, joining at least 27 other state governors in saying they don't want to accept refugees from Syria at least until safeguards and a proper vetting system to guard against terrorists can be implemented.
