Dole, who served Kansas in the Senate for 27 years, passed away at the age of 98 on Sunday morning following a fight with cancer. He was one of the few members of the GOP establishment to support Trump in 2016 and continued praising him in 2020.
Replying to a tweet by The New York Times which spoke of how Dole "overcame grievous war wounds," Hasan wrote his headline: "Bob Dole, who endorsed and voted for Trump twice, and called himself a 'Trumper' as recently as July, has passed away."

Liberals and Conservatives were mad about the privately-educated British anchor for the "zero class" sense.
Former Democrat strategist Lanny Davis replied: "This is in bad taste @mehdirhasan. An unfortunate misjudgment."
Democratic congressional candidate Christopher Hale said: "He fought and was paralyzed in World War II so MSNBC anchors could trash him freely after his recently deceased body was still warm."

"He was also a hero who served his country proudly in WWII. But what does that matter, right?," Conservative radio host Tony Katz chimed in.
But Hasan declined to back down, later insisting: "This is all true, as is the fact that he was a World War 2 veteran, and gave his life to public service, and should be praised for both, but to be clear: 'his GOP' is Trump's GOP - Dole called himself a 'Trumper' and voted for Trump twice. Twice. I can't, or won't, get past that."

The Oxford graduate added: "You can be the most amazing person on earth but if you voted for Trump again after four years of racism and neo-fascism, and 100s of 1000s of dead Americans, that will be remembered and commented upon when it comes time for the obits. Well, by some of us, at least."

Hasan also offered a link to how Trump attacked war veteran Senator John McCain, after his death.
Other commentators supported Hasan's remarks, saying that it was simply true to remember that as well as his military service and political career, Dole threw his support wholeheartedly behind Trump.

"Accurate reporting on former Senator Bob Dole's life will note he served his country admirably for decades, as a soldier and elected leader, before casting his lot with Donald Trump and maintaining that support, even after the insurrection against the United States on January 6th," former Obama Administration official Brandon Friedman said.
Progressive writer Aaron Rupar wrote, "A significant part of Bob Dole's legacy is his staunch support of Trump. He said, "I'm a Trumper" as recently as July."
