In a new video released on the eve of the Democratic convention, a top ranking former official in the Trump Department of Homeland Security says that the president told FEMA to withhold aid to California during the 2017 wildfires.
"He was so rageful," the official, Miles Taylor said, "because people in California didn't support him and it was not a base for him." The section on wildfires starts at about :35 into the video.
According to the New York Times, Taylor is "the most senior former member of the administration to openly endorse Mr. Biden." Taylor expanded on his story in an Op-Ed in the Washington Post.
