It seems you’re referring to Donald Trump’s tendency to reflect criticisms back at his detractors during his campaign, a tactic often described as a “I’m-rubber-you’re-glue” approach. This phrase is based on a childhood taunt meaning, essentially, “whatever you say bounces off me and sticks to you.” This approach has seen Trump deflect criticisms and accusations from himself to his political opponents or other entities. If there are specific events or incidents you would like more information on, feel free to ask!
