Facts don't lie. That's as true now as it was at Donald Trump's January 2017 inauguration.

The estimated turnout at the March For Our Lives demonstration in Washington, D.C. falls at around 800,000. That data point comes from official connected to the demonstration's organizers, speaking to NBC.

It's also a significantly higher number than earlier forecasts had predicted.

Officials connected with today’s #MarchForOurLives here in D.C. tell @NBCNews that they are estimating a crowd size of *800,000* after forecasts of 500,000.

Not to take the focus of the day away from what's important — gun control, and sending a message to politicians who accept NRA dollars — but it's worth noting: The estimated D.C. turnout for March For Our Lives is a great deal larger than popular estimates of the crowd size at Trump's inauguration.

Days after the inauguration, an expert in crowd science compared photos of Trump's with Barack Obama's and deduced that the former attracted roughly one-third the crowd of the latter. It's hard to be exact when dealing with such massive numbers of people, but with Obama's estimated inauguration attendance 1.8 million, Trump's total falls somewhere in the realm of 600,000.

We point this out only because Trump infamously made such a big deal out of his inauguration crowd. He sent his then-White House press secretary Sean Spicer out to proclaim that Trump's crowd "was the largest audience to witness an inauguration, period."

Despite the fact that Spicer's statement was provably false, Trump has never backtracked the claim or publicly backed off his contention.

March For Our Lives isn't the first demonstration to draw a larger crowd than Trump's inauguration — that distinction inarguably goes to the Women's March on Washington, staged one day after the new president was sworn in. But it is the latest, and it should warm your heart to know how much Americans care about putting a stop to gun violence.
