Amy Klobuchar appeared to refuse to shake hands with fellow presidential hopeful Pete Buttigieg after the pair repeatedly sparred during the ninth Democratic presidential debate in Nevada.
The shunning followed a night of hostility between Klobuchar and Buttigieg, with the former South Bend, Indiana, mayor calling out the Minnesota senator for her voting record and a recent interview in which she admitted not remembering the name of Mexican president Andrs Manuel Lpez Obrador, also known as AMLO.
Buttigieg used the slip-up to accuse Klobuchar of not being up for the job as President of the United States.
"I don't think that momentary forgetfulness actually reflects what I know about Mexico and how much I care about it," Klobuchar said during the debate while defending her memory lapse. She then gave a greeting to President Obrador using his full name.
"I am the one person on this stage that came out first to say I was for the US Mexican Canadian Trade Agreement. That is going to be one of the number one duties of a president."
When asked again to comment on forgetting the Mexican president's name, Klobuchar added, "I said that I made an error. I think having a president that maybe is humbled, and is able to admit that here and there, maybe wouldn't be a bad thing."
Buttigieg said forgetting the name of a neighboring country's president is a major error for someone who is staking their candidacy on their experience in Washington.
"You're on the committee that oversees border security. You're on the committee that does trade, you're literally part of the committee that's overseeing these things," he added.
"Are you trying to say that I'm dumb? Are you mocking me here, Pete?" Klobuchar asked.
"He's basically saying that I don't have the experience to be President of the United States," she added. "I have passed over 100 bills as the lead Democrat since being in the U.S. Senate. I am the one, not you, that has won statewide and congressional district after congressional district."
Buttigieg also attacked Klobuchar for voting to confirm President Donald Trump's choice for head of Customs and Border Protection, Kevin McAleenan, who he described as "one of the architects" of the migrant family separation policy at the U.S.-Mexico border.
"You voted to make English the national language," Buttigieg added. "Do you know what message that sends in as multilingual a state as Nevada to immigrants?"
After finishing his remarks with a message to voters in Spanish, Klobuchar replied, "I wish everyone was as perfect as you, Pete."
Speaking to CNN, Klobuchar said she couldn't believe that Buttigieg made the forgetting President Obrador's name "the centerpiece of his criticism."
"I have since many times said the President's name in numerous other interviews, and made it very clear that I know his name."
Klobuchar made no reference of the apparent handshake refusal. Her office has been contacted for comment.
