President Joe Biden used a speech at a steamfitters union hall in Virginia on Thursday to launch an attack against Republicans who control the U.S. House of Representatives, saying some of their proposals are dangerous for the American economy. In his first major economic speech of the year, Biden promoted his record on the U.S. economy, including the creation of more manufacturing jobs, a low unemployment rate and better-than-expected economic growth figures, and lay into the new policies proposed by some Republicans.
