Trump did not attend John Lewis' funeral. Here are 4 other major funerals he missed while president.

Democratic Rep. Elijah Cummings' funeral service took place last October in his hometown of Baltimore, Maryland, part of the district he represented since 1996. The former chairman of the powerful House Oversight and Reform Committee, who helped lead the impeachment inquiry of President Donald Trump that was taking place at the time, died at age 68.

In the months leading up to his death, Trump engaged in an escalating public feud with the congressman, calling him a "racist," launching attacks at Baltimore, and appearing to mock a reported burglary at his home.

Trump skipped the funeral. A copy of the president's schedule that day showed he had nothing on his agenda at the time.

Former Presidents Barack Obama and Bill Clinton and former First Ladies Michelle Obama and Hillary Clinton were all in attendance, among many other key lawmakers and high-ranked officials, including now Trump's chief of staff Mark Meadows, who delivered a tearful speech in honor of his "dear friend."

Rep. John Dingell, the longest-serving member in Congress ever at more than 59 years, died at age 92 last February. A funeral service in Washington, DC, was attended by former President Bill Clinton and former Secretary of State Hillary Clinton, as well as former Republican House Speaker John Boehner, among others. Former Vice President Joe Biden attended another funeral held in Michigan, Dingell's home state.

Trump was not at either funeral, but he ordered American flags to be flown at half-mast after Dingell's death to honor him. Months later, Trump suggested the Democratic congressman might be in hell aftter his wife, Rep. Debbie Dingell (D-Mich.), voted to support impeachment.

"Maybe he's looking up, I don't know," Trump said during a campaign rally in Michigan. "But let's assume he's looking down."

Rep. Debbie Dingell called his comment a gut punch.

In perhaps the most controversial of Trump's missed funerals, the president did not attend the late Arizona Sen. John McCain's ceremony in September 2018 because he was not invited.

Cindy McCain, the senator's wife, explained that she wanted the service to remain "with dignity."

"Even though it was a very public funeral, we are still family. For all of us and for the sake of my own children, I didn't want any disruption. This was about John, not about anything else at all," she said at the time.

Trump's daughter Ivanka and her husband Jared Kushner, and other members of his administration attended the funeral.

The president had been in a longtime dispute with the late senator, hurling insults at the revered naval officer who died aged 81 after a battle with cancer. McCain, who was much admired by politicians from both sides of the aisle, had not shied away from speaking out against Trump, unlike many from within his party.

Trump continued to spew repeated attacks against McCain even after his death.

Former First Lady Barbara Bush's funeral held in Houston, Texas, was attended by more than 1,000 people. Trump was not one of them.

She died in April 2018 at the age of 92 and was remembered as a beloved public figure of the World War II generation. Her husband, the late former President George H.W. Bush was at the service with his sons, former President George W. Bush and former Florida Gov. Jeb Bush.

Among the people gathered also included the Obamas and Clintons, as well as First Lady Melania Trump.

White House officials noted in advance that President Donald Trump would not attend "to avoid disruptions due to added security, and out of respect for the Bush family and friends attending the service."
