(CNN) An outside group aiming to help Joe Biden's presidential candidacy amid attacks from President Donald Trump officially launched Wednesday with a video and announcement of its team, which is comprised of veteran Democratic strategists and former aides to Biden.

"We are committed to fighting back against Trump, his allies, the Russians, and the Republican Party -- all of whom are engaged in unprecedented attacks against Vice President Biden in order to deny him the Democratic nomination," Mark Doyle, chairman of Unite the Country, said.

The minute-long video features Biden's own words: "We can unite this country. Folks this is the United States of America. Stand up. Take it back. We can in fact do anything we set our mind to. This is the United States of America."

The board of Unite the Country includes Doyle, a former Biden aide who will serve as chairman; John MacNeil, who worked on Biden's 2008 campaign and will act as secretary; and Larry Rasky, who was a part of Biden's 1988 and 2008 presidential campaigns and will act as treasurer. Mark Riddle, executive director of Future Majority, and Michèle Taylor, a former vice chair of the finance committee for the Democratic National Committee, will also serve on the board.

Amanda Loveday, a former aide to Rep. James Clyburn of South Carolina; Steve Schale, Florida Director for Obama's 2008 presidential campaign; and Julianna Smoot, deputy campaign manager for Obama's 2008 campaign, have also come on board to join the Unite the Country team.
