As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Trump has long admired the British royal family and his big birthday parade in Washington is the same day as the U.K.’s annual Trooping the Color.

The new poll from The Associated Press-NORC Center for Public Affairs Research found that 60% of Americans believe the military parade is not a good use of government funds while 38% said that it is. The parade is meant to commemorate the 250th anniversary of the U.S. Army, but it is also being held on Trump’s 79th birthday on Saturday.
