Hillary Clinton Booed at Trump Inauguration: ‘Lock Her Up’

As Hillary Clinton, along with husband former President Bill Clinton, were announced at President Donald Trump’s Inauguration Day ceremony, a familiar chant was heard.

“Lock her up. Lock her up.”

According to a video feed, another person could be heard saying, “That’s not nice.” CNN reporter Teddy Davis said that it was a Trump supporter who spoke those words to the anti-Clinton chanters.

Boos were also heard during the announcement.

The three-word phrase was popular at Trump rallies across the U.S.

Clinton, meanwhile, wrote on Twitter that she’s attending the inauguration to “honor our democracy.”

“I’m here today to honor our democracy & its enduring values. I will never stop believing in our country & its future. #Inauguration,” she wrote in full.
