This past Saturday, an estimated crowd of close to 800,000 people attended the "March for Our Lives" rally in Washington, D.C. to protest against gun violence and call for reform. After it was reported that Donald Trump spent the day golfing, one of the lead voices in the movement decided to call out the president on social media.

It was just over a month ago when 19-year-old Nikolas Cruz walked into the hallway of Marjory Stoneman Douglas High School in Parkland, Florida and opened fire.

Over the course of the next few minutes, 17 innocent people had been killed, with many others left injured. In the time since, a growing number of student activists have spoken out in opposition to the NRA and more pro-gun rights politicians, which has created headlines due to the push back from many conservatives. One of the students who has found himself in the spotlight is David Hogg, who has appeared on CNN, MSNBC, CBS, and other news and media outlets to push for gun reform.

David Hogg was in attendance in Washington, D.C.

over the weekend for the "March for Our Lives" rally, which is reported to have had as many as two million demonstrators taking part in over 800 additional rallies around the country. Donald Trump, however, decided to avoid the rally since it conflicted with his political position, and spent time golfing at his resort in Florida.

In response, David Hogg took to Twitter on March 25 to throw shade at the president. "I hope some of you had a great weekend golfing I had a great time marching with the American people," Hogg tweeted.

"I guess you could say the March was a hole-in-one and on the first hole too!

So proud of you guys this is a great start yesterday was the birth of a revolution," David Hogg added in a follow-up tweet. Not stopping, there, Hogg decided to continue his feud with Florida Republican Sen. Marco Rubio by responding to a tweet sent out by the NRA-supporting Rubio.

"Americans with opposing views can achieve meaningful change together when we reach out to each other & work to find common ground," Marco Rubio tweeted out while attaching a video clip of families of several Parkland shooting survivors. In response, David Hogg had something to say.

"You can too Rubio, by denouncing the NRA or resigning.

I'll gladly pay the $1.05 for you to do so," David Hogg tweeted out. "Denounce them and join the revolution, for you know how these people at the NRA scare and manipulate politicians far more than anyone," he added.
