In February 2016, presidential candidate Jeb Bush speculated that Trump had mental health issues, stating "I'm not a psychiatrist or a psychologist, but the guy needs therapy".[8][9] In early 2017, psychologist John Gartner collected more than 25,000 signatures of mental health professionals on a petition, directed to the national opposition leader, Democratic Senator Chuck Schumer.[10] At the end of April 2017 he was able to forward the petition with more than 41,000 signatures of mental healthcare professionals to Washington D.C..[11] The core of the petition stated: My professional judgement is that Donald Trump manifests a serious mental illness that renders him psychologically incapable of competently discharging the duties of President of the United States. And I respectfully request him be removed from office, according to article 3 of the 25th Amendment, and so on. Gartner asserted that Trump's mental handicaps are a mix of 1. narcissism, 2. paranoia; 3. sociopathy; and 4. a dash of sadism.
