Powell writes that Trump "is in the process of destroying himself, no need for Dems to attack him."In another email Powell describes Trump's birther investigation as a "racist" movement that incorrectly suggests Obama was born in a foreign country."Yup, the whole birther movement was racist," Powell wrote. He also said Trump wanted to know if Obama was a Muslim. "As I have said before, 'What if he was?' Muslims are born as Americans everyday."In a separate email titled " racism ," Powell writes, "There is a level of intolerance in parts of the Republican Party ."Buzzfeed reports that it obtained the emails from the website DCLeaks.com, a group that is suspected of having ties to Russian cyber spies.
