Pete Souza has absolutely had it with President Trump and he's not holding anything back.

After Trump announced that the U.S. was officially pulling out of the Paris Climate Agreement on Thursday, a disappointed Souza shared his grief by posting a photograph of Obama's signed Paris Agreement acceptance letter.

Now he's coming for Trump with a series of powerful Instagram posts: photographs of the Obama family enjoying the wonders of our natural world, each captioned with lyrics from the popular traditional american song, "This Land Is Your Land."

On Friday morning, Obama's former White House photographer shared a stunning photograph of Barack, Michelle, Malia, and Sasha at Acadia National Park in Maine.

He simply captioned the throwback, "This land is your land. This land is my land." With the first lyric to the iconic anthem, he appears to have set off on making another of his classic political statements through social media.

About 20 minutes later, Souza posted another nostalgic photograph of Obama standing alone in California's Yosemite National Park, overlooking some mountains and admiring his surroundings. The second Instagram post was captioned, "From California to the New York Island," aka the second line from "This Land is Your Land."

After about another 20 minutes Souza hit us with a third adorable photo Of Obama and his daughter Sasha in the water at Panama City Beach, Florida. As you can guess, it was captioned, "From the Redwood Forest, to the Gulf Stream waters."

A fourth post, captioned "This land was made for you and me" came, showing Obama with children in Everglades National Park in Florida.

And yet another photo showing the Koko Head Hiking Trail in Hawaii.

He shared one more of Obama checking out that endless skyway in Alaska's Kenai Fjords National Park.

And another of our former POTUS chilling in Oahu in some fresh kicks.

Then came a breathtaking shot from Mount Mansfield in Vermont, which Souza captioned, "This land was made for you and me. The future depends on all of us."

After Trump's announcement on Thursday, Souza post the following photo with the caption, "He tried. But we failed our children." Souza seemed to be very emotionally affected by the decision, so it's no surprise that he's not ready to let Trump off the hook just yet.

It should, however, be noted that the song Souza is referencing, by Woody Guthrie, was originally seen in 1940 as an angry, progressive response to Irving Berlin's "God Bless America." His original lyrics actually included a reference to a big wall. (Ugh.)

There was a big high wall there that tried to stop me.

The sign was painted, said 'Private Property.'

But on the backside, it didn't say nothing.

This land was made for you and me.

Since then the song has transformed into a classic patriotic anthem of America. And from what we know about Souza's impressive ability to Insta-troll Trump while simultaneously pointing out all the things he loved about Obama's presidency, we have a feeling Souza will keep the posts coming, line by line.

And rest assured, if he does continue, we'll be sure to update this article accordingly.
