Simpson was among those who paid tribute to Bush during the state funeral at the Washington National Cathedral Wednesday. The 41st president died late Friday at the age of 94.

"He was just a delicious guy. There was nobody ever like him," said Simpson, who represented Wyoming from 1979 to 1997 and had a friendship with Bush that spanned more than 50 years.

The nation's politicians can take a page from the life story of former President George Herbert Walker Bush, former Sen. Alan Simpson told CNBC on Wednesday.

Former US Sen. Alan Simpson shakes hands after speaking during the state funeral of former US President George H.W. Bush at the Washington National Cathedral in Washington,DC on December 5, 2018.

In his eulogy, Simpson said Bush "often said when the really tough choices come, it's the country, not me. It's not about Democrats or Republicans, it's for our country that I fought for."

Simpson told CNBC there were two gems he and his friend lived by: "Hatred corrodes the container it's carried in" and "humor is the universal solvent against the abrasive elements of life."

"They ought to learn this around this joint," said Simpson, speaking from the nation's capital shortly after the funeral ended.

However, he insisted he was not targeting anybody, only reflecting on Bush's life.

"There's too much targeting going on around this place," he said.

"Life is really not all real chaos and 24-7 news," he added. "It's called silence and meditation and reflection and, for God's sake, it's clarity. It's not about complexity and confusion. You've got to sort out the crap. It'd be a good thing for them to start doing. That's good for the world."

Bush's funeral brought President Donald Trump and former Presidents Barack Obama, Bill Clinton and Jimmy Carter together in the same row at the front of the National Cathedral. It was a moment that some called extraordinary for the basic level of civility shown during this tumultuous time in politics.

"It is still nice to be kind and decent and you can still be tough and ornery and partisan. God knows I am," Simpson said. "But down at the bottom of bowels in your gut, you've got to have manners and you've got to have love and that's tough for people even to admit in these times."
