President Donald Trump claimed Tuesday that his predecessor did not take action to reform policing — although it was the Trump administration that scrapped several Obama-era changes.

"The reason they didn't try is they had no idea how to do it," Trump said of Barack Obama and Joe Biden during a Rose Garden ceremony to sign an executive order on policing measures. Biden deputy campaign manager Kate Bedingfield shot back, "He knows that isn't true because he has spent the past three years tearing down the very reforms the Obama-Biden administration pursued."
