President Donald Trump began his weekend early, sending out a tweet Saturday calling for those who voted to "Make America Great Again" to have their own rally, which would be the "biggest of them all."

Sen. Bernie Sanders (I-VT) however was quick to respond, tweeting that the "rally" already happened at the Inauguration and it was not the biggest of them all. He included side-by-side photos of the National Mall in Washington, D.C., comparing the crowds from Trump's Inauguration to those from the D.C. Women's March, which took place the following day.
