Has No Idea': Trump Crumbles After Being Put on the Spot About His Bold Claim, and His 'Explosive' Answer Has the Internet Howling

President Donald Trump stumbled when pressed to provide evidence for a claim that the MMR vaccine could be “quite lethal.” During a Monday Oval Office exchange, he did not cite a study, medical expert, or public health agency, instead saying he had “heard some people say it is that way” and that combining the three vaccines could be “explosive.” The White House event came as Trump signed an executive order to overhaul childhood vaccination recommendations, including a push to separate the MMR into three shots across different visits and to narrow the vaccines routinely recommended for all children while placing others into categories for high-risk children or shared clinical decision-making. The CDC says the MMR has been used for decades and rarely causes serious adverse reactions, and extensive research has found no link to autism.
