April 15, 2021 Tight numbers could plague the Democratic majority for months, but top Democrats insist they can hold their caucus together. SHOW TRANSCRIPT Since the start of the 117th Congress, six seats in the House of Representatives have become vacant — creating a razor-thin Democratic majority trying to pass ambitious legislation, including a $2 trillion infrastructure package. Of the vacancies, four are Democrats, three of whom resigned Congress to join the Biden Administration. The fourth, 15-term Congressman Alcee Hastings, died earlier this month after a battle with pancreatic cancer. Republicans currently have just one vacant seat after Wednesday's swearing in of Louisiana Congresswoman Julia Letlow, the widow of the late Congressman-elect Luke Letlow, who died from complications of Covid-19 before he was able to take office.
