A group of House and Senate Democrats who attempted to access the headquarters of the U.S. Agency for International Development (USAID) on Monday were denied entry. Why it matters: It's likely the first physical standoff between congressional Democrats and the second Trump administration — though it may not be the last as Democrats ratchet up their resistance to the new president.

The move would require Senate Majority Leader John Thune to use precious floor time to advance the president’s nominees through the confirmation process.

Senate Democrats are plotting to retaliate against the Trump administration after attempts to restructure or possibly close the U.S. Agency for International Development (USAID), which provides foreign aid and supports democracy around the globe.
