'No line he can cross': Trump's niece reveals his 'obsession' has infected GOP

Mary Trump, the niece of President Donald Trump, revealed during a recent podcast interview that the president is driven by an "obsession" that appears to have infected the GOP.

President Trump has displayed some "completely indecent" behavior recently, according to his niece, including the mind-boggling statement he issued after director Rob Reiner and his wife, Michelle, were murdered in their Los Angeles home. Trump blamed Reiner's killing on "Trump Derangement Syndrome," a made-up disease Trump uses to demean his critics.
