The Most Talked About Moments You Can't Miss from Joe Biden's Inauguration

In an effort to maintain safe social distance practices throughout the historic day, politicians were seen bumping fists and tapping elbows to greet each other.

Vice President Harris chose purple to unify her look for a meaningful reason. CNN's Abby Phillip pointed out during Inauguration Day coverage that Harris used purple and yellow as colors to launch her presidential campaign — a nod to Shirley Chisholm, who became the first Black woman elected to the United States Congress. Chisholm would later run for president in 1972. Phillip noted that Chisholm's boundary-breaking trajectory in politics in part inspired Harris' career.

Wearing a suffragette white Chanel ensemble and symbolic pearl earrings, Lopez dazzled on stage with renditions of "This Land Is Your Land" and "America the Beautiful" during the inauguration festivities.

"Una nación, bajo dios, indivisible, con libertad y justicia para todos," the Puerto Rican singer said in Spanish, before referring to her track, "Let's Get Loud." ("One nation, under God, indivisible with liberty and justice for all," in Spanish.)

As Jennifer Lopez belted out the lyrics to her 1999 hit "Let's Get Loud" as part of her rendition, Twitter chimed in with takes on her medley.

"Was that a This Land is Your Land, Lets Get Loud mashup?!?!" a user tweeted.

"I hope when all our future children sing “This Land is Your Land” that a dramatic “LETS GET LOUD!!!” will forever be part of it," another added.

There to perform the national anthem, Lady Gaga was beaming as she arrived at the Capitol. The singer sang beautifully while Twitter began to light up with comments about her Hunger Games-esque look. Her large accessory was a peace dove carrying an olive branch, her nod to a hopeful future under the Biden administration. 

The singer's symbolic golden pin of a dove carrying an olive branch was another piece that made Twitter's Hunger Games comparison seemingly more valid.

"who else tossed up three fingers when lady gaga walked out in hunger games cosplay," a social media user quipped.

Twitter also had some fun with this photo of Sen. Bernie Sanders waiting for the ceremony to begin. Hilarious tweets poured in, describing Sanders as a hashtag mood, including the following:

“This could’ve been an email,” one social media user tweeted.

"Bernie is me at all family events," another wrote.

Sanders later clarified his choice in warm winter gear, telling CBS, "In Vermont ... we're not so concerned about good fashion. We want to keep warm."

Sanders' mittens also caused conversation, as New York Times fashion critic Vanessa Friedman noted in a tweet, "In all the inauguration fashion news, let us not overlook Senator Bernie Sanders’ mittens."

Turns out, Sanders' mittens hold special meaning. Jen Ellis, a teacher from Essex Junction, Vermont, made them for him a few years ago and even makes similar styles for those interested in a pair.

"I made Bernie's mittens as a gift a couple years ago. They are made from repurposed wool sweaters and lined with fleece (made from recycled plastic bottles). #BerniesMittens," Ellis wrote on Twitter.
