After becoming mayor of London, Sadiq Khan immediately whined that he wouldn't be able to visit the US if Donald Trump were elected. He also pledged to help Hillary beat Trump in the November elections:
Trump congratulated Khan on becoming London's first mayor, and said Khan would be allowed into the US in spite of his proposed ban on Muslims.
Khan responded by immediately issuing a statement that he would reject any exemption out of principle. Wonder if he'll reject Mecca's ban against non-Muslims traveling there?
Meanwhile, Newt Gingrich is one of the leading choices for Trump's VP:
A very good choice - a political operator, as per Trump's requirement, and someone who could garner votes from Reagan-era supporters, as well as step into the Presidency if something happens to Trump.
