Democratic presidential hopeful Senator Bernie Sanders held a campaign rally in Springfield, Virginia on Saturday.

Sanders was campaigning in Virginia as voters in South Carolina voted in that state's presidential primary.

He chided President Donald Trump describing him as the "most dangerous president" in modern American history.

"We are going to defeat Donald Trump because we are putting together an unprecedented, multi-racial, multi-generational grassroots movement the likes of which this country has ever seen," Sanders told his supporters.
