Biden Removes Mask and Immediately Coughs into Hand

Biden said during a signing ceremony in the State Dining Room that the legislation, called the Inflation Reduction Act, is "one of the most significant laws in our history."

"With this law, the American people won and the special interests lost," Biden told an audience of Democratic members of Congress and administration officials. "For a while people doubted whether any of that was going to happen, but we are in a season of substance."
