Obama warns against 'purity tests' in Democratic primary

Former President Barack Obama is warning Democrats against adopting "purity tests" in the presidential primary and alienating voters needed to defeat President Donald Trump in the general election.

Obama spoke yesterday before about 100 donors during a question-and-answer session with Democratic National Committee Chairman Tom Perez in Los Altos Hills, California. The event came a day after the fifth Democratic presidential primary, which featured 10 candidates.

Obama urged Democrats to "chill out," saying, "The truth of the matter is that every candidate on that stage believes we should provide" better health care and education and address climate change.
