“Just like we drew it up, @Chiefs,” Mr. Biden’s account wrote on social media after the game, along with an image that paid a homage to his “Dark Brandon” alter ego, an edgier and more online version of the president, if he could shoot laser beams out of his eyes.
Ms. Swift has waded into politics in the years since the 2016 presidential race, when she was criticized for avoiding an endorsement and observers speculated over her political beliefs. In 2018, ahead of the midterm elections, she wrote on Instagram she would vote for Phil Bredesen, the Democratic challenger to Senator Marsha Blackburn, a Republican of Tennessee. (Ms. Blackburn won.)
A clip from her 2020 documentary “Miss Americana” showed that the deliberation behind Ms. Swift’s decision to endorse Mr. Bredesen was more intense than was publicly known. In that clip, a tearful Ms. Swift told her father that she needed to be “on the right side of history” and that “if he doesn’t win, then at least I tried.”
In that conversation, her father, Scott Swift, warned her about the danger of getting involved in politics, saying that he had to order “armored cars” to keep his daughter safe.
In October 2020, Ms. Swift endorsed Mr. Biden in an interview with V Magazine.
“I will proudly vote for Joe Biden and Kamala Harris in this year’s presidential election. Under their leadership, I believe America has a chance to start the healing process it so desperately needs,” she said at the time.
Tree Paine, a representative for Ms. Swift, did not immediately return a request for comment on Monday asking whether the singer would travel to the White House or whether she planned to endorse Mr. Biden.
