Sen. Cory Booker (D-NJ) on Friday announced that he would be seeking the Democratic nomination for president to challenge President Donald Trump in 2020.


"The history of our nation is defined by collective action; by interwoven destinies of slaves and abolitionists; of those born here and those who chose America as home; of those who took up arms to defend our country, and those who linked arms to challenge and change it," Booker said in an announcement video released Friday. "I'm Cory Booker and I'm running for president of the United States of America."

In the announcement video, Booker detailed how his family had difficulty being able to buy a home in they neighborhood they wanted to live in until a group of white attorneys, who were inspired by the civil rights struggle in the 1960s, decided to help black families beat housing discrimination.

"In America, courage is contagious," Booker said.
