Donald Trump took to social media on Tuesday to do something most people might not have thought he would — take up for former President Joe Biden while bashing those he called “treasonous thugs.” And, while doing so, Trump laid out a myriad of claims and accusations that, to date, have not been proven.

President Donald Trump has said that those around Biden "knew he was cognitively impaired" and "took over the autopen" during his presidency.

A new book called "Original Sin," written by two journalists, alleges steps were taken to conceal former President Joe Biden's declining health while in office. CBS News White House reporter Aaron Navarro has more details.
