On Monday, a Presidential Inaugural Committee spokesperson confirmed that Underwood would perform at Trump's upcoming inauguration.
After the news broke, a recent Instagram post from Underwood became inundated with leftists slamming her for her upcoming performance.
"Have been a fan of yours from the beginning but just heard you will be singing at Trump's inauguration," one disgruntled fan commented. "Just lost all respect for you. How can you support someone so hateful? Sad to hear this news."
"Heartbroken. Always loved you. Won't support your actions," wrote another angry fan.
Brett Cooper, formerly of The Daily Wire, noted that Hillary Duff had previously performed at President George W. Bush's second inauguration in 2005.
"Did she get canceled? Did she get called a bigot and a traitor because she performed for a Republican president?" Cooper asked. "No. People loved her, Bush said she was awesome, it was fun."
"Let’s bring that energy back. It’s an insane opportunity, a historic moment, and Carrie Underwood will crush it," she added.
Later Monday, Underwood commented on the announcement.
“I love our country and am honored to have been asked to sing at the Inauguration and to be a small part of this historic event,” the American Idol winner said in a statement to PEOPLE.
“I am humbled to answer the call at a time when we must all come together in the spirit of unity and looking to the future.”
