Trump, Obama, Bush and Clinton Share 9/11 Tributes on Tragic Anniversary

​Former Presidents Donald Trump, Barack Obama, George W. Bush, and Bill Clinton shared tributes on Sunday commemorating the 21st anniversary of the tragic 9/11 terrorist attacks.

On his social media platform, Truth Social, Trump posted an illustrative picture of the date 9/11 portrayed in the American flag with the words "Never Forget."

In another Truth Social post, he wrote: "Twenty-one years ago, the World was changed forever. We will always remember the 2,977 lives lost and the many selfless heroes who emerged on that day. God bless all of those incredible souls, and God bless the USA!"

Meanwhile, Obama posted a picture of himself with his wife Michelle, the Clintons and the Bidens, paying tribute to those who died on that fateful day and tweeted: "Today, we remember the nearly 3,000 lives we lost on September 11, 2001. We honor their memory, the courage of our first responders, and the men and women in uniform who continue to keep us safe."

The George W. Bush Presidential Center posted a brief clip on Twitter, showing a piece of steel from one of the World Trade Center towers.

"This is a piece of steel from the World Trade Center. It's a powerful reminder of our duty to honor the victims, support our first responders and military, and remember the lessons from that day," the presidential center wrote on Twitter.

"May God Bless the memories of the victims of 9/11, and may He continue to bless the United States of America," a tweet from Bush read underneath.

Meanwhile, Clinton tweeted: "As we remember all those who lost their lives and loved ones 21 years ago, the greatest tribute we can pay is to serve, give back, and improve the lives of others—today and every day."

The Carter Center, which was founded by former President Jimmy Carter, posted a brief statement on Twitter in remembrance of the tragic attacks, reading: "Today we honor the memory of those who died in the Sept. 11, 2001, terrorist attacks, and we salute the first responders who sacrificed so much that day. We pledge to continue to work to build a world where everyone can live in peace."

On Sunday afternoon, Biden paid tribute to police officers, firefighters, the passengers on Flight 93, and the civilians and service members who took action on that day 21 years ago. He also honored thousands of Americans who enlisted in the Army "to protect our nation."

Earlier in the morning, Biden wrote: "Twenty-one years later, we keep alive the memory of all the precious lives stolen from us at Ground Zero, in Shanksville, Pennsylvania, and at the Pentagon. To the families and loved ones who still feel the ache, Jill and I hold you close in our hearts. We will never forget."

During a Sunday speech commemorating the anniversary, the president brought up last month's U.S. drone strike that killed Ayman al-Zawahiri, who became the leader of Al-Qaeda after Osama bin Laden was killed in 2011. Zawahiri also helped plan the terror attacks that unfolded on 9/11.

"Through all that has changed over the last 21 years, the enduring resolve of the American people to defend ourselves against those who seek us harm and deliver justice those responsible for the attacks against our people has never once faltered," Biden said.

He added: "It took 10 years to hunt down and kill Osama bin Laden, but we did. And this summer, I authorized a successful strike on Zawahiri—the man who bin Laden was his deputy at 9/11 and was the leader of Al-Qaeda—because we will not rest. We'll never forget, we'll never give up and now Zawahiri can never again threaten the American people."
