Former President Donald Trump on Saturday disputed the 2020 presidential election results and repeated many of the baseless claims of voter fraud he leveled at his last campaign-style rally nearly six months ago. Mr. Trump’s previous rally, on Jan. 6, preceded a riot in the U.S. Capitol in which pro-Trump supporters attempted to stop then-Vice President Mike Pence and a bipartisan majority of Congress from certifying President Joe Biden’s victory.

The nation has continued to grapple with both political and legal repercussions of that day. House Democrats plan a select committee to investigate the events that led to the attack; Senate Republicans blocked the formation of a bipartisan, independent commission, which Senate Minority Leader Mitch McConnell (R., Ky.) said was an unnecessary political exercise that Democrats would weaponize against Republican candidates.

Meanwhile, more than 500 Americans have been arrested and charged with crimes in connection to the violence, including at least 100 accused of assaulting police. Mr. Trump didn’t mention the attack during his rally, which drew thousands of supporters to the Lorain County fairgrounds, about 60 miles southwest of Cleveland.
