House Minority Leader Nancy Pelosi struggled to say President Trump's name during a forum at the Commonwealth Club of California, and admitted that Hillary Clinton's loss in the presidential election was "a blow" that's difficult to accept.

Pelosi, a Democrat and former House Speaker who represents San Francisco, referred to Trump at one point as "what's his name," and said she would "honor the position" by referring to Trump as president of the United States, even if she did not include his name.

"I don't know, from what I've seen, how much respect he has for the job," Pelosi said.

Pelosi confessed she would "do anything" to have George W. Bush as the GOP president over Trump. She recounted her first sit-down with Trump in a January White House meeting with congressional leaders that had traditionally been kept private. Pelosi spilled the details, which Democratic leaders leaked months ago, recalling for the Commonwealth Club audience that Trump's first words to her included the erroneous claim that he would have won the popular vote if not for massive voter fraud.

Pelosi said she told Trump his claim was untrue and added, "if you are not going to stipulate to a set of facts, it's going to be very hard for us to negotiate and make progress."

Pelosi criticized Trump's recent trip to the Middle East and Europe and said his decision not to reaffirm U.S. commitments to aid NATO countries under Article 5 of the treaty "is a gift to Vladimir Putin."

Pelosi talked to the club about immigration reform, healthcare reform and the 2018 election, on which she said she is "optimistic" that Democrats can regain control of the GOP-led Congress.

Pelosi repeated her support for a single-payer healthcare system and said she would not compromise with Republicans on an immigration reform plan that would merely legalize the 11 million people now living in the United States illegally.

Pelosi said an immigration reform plan would have to provide a pathway to citizenship.

"You can live here but you can't vote here?" Pelosi said. "There should be a pathway to citizenship."

Pelosi also talked about her family and growing up in a political family. Her father was the mayor of Baltimore.

But, she said, "My mother wanted me to be a nun."
