Donald Trump took a rare swipe at Michelle Obama on the campaign trail on Friday. For much of the campaign, the Republican nominee has avoided directly challenging the first lady. Polls show she is far more popular than her husband or the two presidential nominees. But at a rally Friday in North Carolina, Trump complained that “all she wants to do is campaign ”. He then accused her of attacking Hillary Clinton during the 2008 primaries. At the same rally Trump said the Philippine president’s shift toward closer relations with China after decades of a pro-U S foreign policy showed that “America has grown weak” and implied that Barack Obama had neglected his presidential duties as he was often campaigning for Democratic candidate Hillary Clinton.
