In previous years, the White House has been lit up in various colors to celebrate or honor particular causes that presidents supported. For example, Trump lit the White House blue in early April to honor World Autism Awareness Day.

However, some presidents have been criticized for not lighting up the White House. Former President Barack Obama came under fire in July 2016 for refusing to light the White House blue in support of law enforcement after five officers were slain in Dallas, Texas. Nate Catura, president of the Federal Law Enforcement Officers Association, called Obama's decision "outrageous."

After the Federal Law Enforcement Officers Association sent a letter to the White House requesting blue lights in honor of the fallen officers, Obama's press secretary, Josh Earnest, replied, "That's not something that we plan to do at this point."

But Obama did illuminate the White House in rainbow colors in celebration of the Supreme Court ruling that allowed same-sex couples to get married in June 2016.
