Three senior House Democrats are urging President Donald Trump to reconsider his plans to speak at the Fourth of July celebration on the National Mall.

House Majority Leader Steny Hoyer, Natural Resources Chairman Raúl Grijalva (D-Ariz.) and Rep. Betty McCollum (D-Minn.), who oversees the Appropriations subpanel that funds Interior, expressed fears Trump’s plans “could create the appearance of a televised, partisan campaign rally on the Mall at public expense” and waste taxpayer dollars.

“For decades, the Fourth of July on the National Mall has been non-partisan and apolitical,” they wrote in a letter Thursday. “We respectfully call on you to look for ways to complement, not conflict with, the Fourth of July celebration, such as considering an earlier time or alternative location for your remarks.”
