The Biden administration's latest $2.3 trillion spending proposal designates a lot of money to improving roads, bridges, and airports, and expanding broadband. But many Republicans think it should solely focus on infrastructure, and bristle at the inclusion of what they consider separate issues. In an apparent effort to counter that argument, Sen. Kirsten Gillibrand (D-N.Y.) tweeted Wednesday that child care, caregiving, and paid leave are, in fact, infrastructure. The message didn't land the way she hoped, it seems.
