Lin-Manuel Miranda and some of his fellow cast members from the musical “Hamilton” participated in a congressional commemorative event Thursday marking the anniversary of the Jan. 6, 2021, attack on the Capitol.

“We’re all stewards of the American experiment, working to pass down to our children and our grandchildren a more perfect union that treats all its citizens with fairness and equity. We should never take our rights and liberties for granted,” Miranda, who was introduced by Speaker Nancy Pelosi (D-Calif.), said in remarks that appeared to be pre-recorded.

The “Hamilton” creator said that Americans need to continue striving toward unity, saying no obstacle “is worth abandoning our efforts.”

“And we must remain committed to finding a way forward together. That’s what I wrote about in the song ‘Dear Theodosia’ from ‘Hamilton.’ I believe no challenge is worth abandoning our efforts to unite as Americans. We will keep working generation after generation until we reach that someday,” Miranda said before a video was shown of a performance of the song.

The remarks and song were part of Congress’s commemorative events on Thursday that marked one year since a pro-Trump mob stormed the Capitol and tried to stop lawmakers from certifying the 2020 presidential election results. 

Earlier, Pelosi led a moment of silence on the House floor.

“Today, we accept responsibility as daunting and demanding as any previous generations of leadership have faced,” she said. “As we reflect on that darkest day, we remember that the insurrection sought not only to attack the building, but to undermine democracy itself.”
