Joe Biden whispers several times during remarks on 'bipartisan' infrastructure bill

President Joe Biden presented the 'bipartisan' infrastructure bill to the press and public today.
Biden gave the green light to a $1.2 trillion Senate deal to renew the nation's roads, bridges, and highways.
During the press conference, Biden hunched over the podium and whispered the answers to questions being asked about who will pay for this and how will the bill work. It all seemed very bizarre.
