"I'd like to thank my colleagues for the opportunity to serve as the House Republican conference chair. I have prioritized listening to all members of our Republican conference, and my focus is on unity because that's what the American people and that's what our voters deserve," she said.
Stefanik thanked former President Trump for his support and called him "a critical part of our Republican team."
The New York lawmaker slammed President Biden and House Speaker Nancy Pelosi's policies, saying the GOP will fight against their measures.
"The American people are suffering under the far left radical socialist policies of President Joe Biden and Speaker Nancy Pelosi. In just over 100 days, we have an economic crisis. We have a border crisis. And we have a national security crisis," she told reporters.
Stefanik said she is "very excited" for the opportunity to be conference chair, and said House Republicans are "unified working as one team."
"The American people know that the stakes are incredibly high. We are going to fight for them each and every day against the destructive, radical far left socialist agenda of president Joe Biden and Nancy Pelosi that's destroying America," she said.
