US Vice President Kamala Harris, who serves as chair of the National Space Council, was enthusiastic about science in a NASA video for kids, but her exaggerated facial expressions and wide-eyed enthusiasm became reasons for netizens to have a good laugh.

In a NASA video on YouTube honoring World Space Week, she had an interaction with children about "craters on the moon" and more.

She hosted children at her residence in Washington, D.C., where the US Naval Observatory is located, where she also gave them some advice, reported Fox News.

She said in the video that one of the most important pieces of advice that she can offer to the kids is, "Never let anybody tell you who you are, you tell them who you are." She told them not to let anybody suggest to them that they are what others think they should be instead the kids should tell others who they are and what they intend to be.

Apart from giving advice on life, Harris also talked about her passion for science and "exploring the unknown." She and the kids traveled to the observatory and she said, "Wait until you guys see the moon. I just, I don’t know what it is about those craters on the moon." She told the kids to have big dreams.

One Twitter user asked if she was qualified to talk about space exploration to kids, and said that she should stick to what she knows. Another compared her laughter to that of a hyena's, and asked why she wasn't in Mexico despite being in charge of the border crisis.

On Friday, many top members of the Biden administration were in Mexico City for a meeting with Mexican officials to discuss security along the US-Mexico border, but Harris skipped it, according to Fox News.

Secretary of State Antony Blinken, US Attorney General Merrick Garland and Homeland Security Secretary Alejandro Mayorkas attended the Friday meeting in Mexico's capital. Mayorkas tweeted Friday that the high-level security dialogue marked a significant "new phase in the US-Mexico security partnership."

He said that they will work together under a new framework to guide their joint efforts, and work toward their shared goals of prosperity and security for the two countries.

Harris was appointed by President Joe Biden in March to manage the US response to the migrant crisis along the border, but instead of meeting the Mexican officials last week, she headed to New Jersey. Rather than focusing on the border crisis, she was promoting the Biden administration’s agenda in Newark, New Jersey where she visited a vaccination site apart from going to a daycare center at Montclair State University.

The last time she visited the border was in June this year, when she spent hours in El Paso, Texas, and it is the only time she’s been to the border since taking up the responsibility.
