That's not even close to a record. Trump lied 30,573 times during his failed term in office, and in his last year, he lied over 50 times a day during August, including 189 times on August 11. He is far, far ahead of anything Biden could achieve in the lie department, even if he tried. Trump was and is incapable of being truthful, which is what his attorney told Robert Mueller when he begged him not to depose Trump.
