"It is the Democratic Party that is the party of slavery, the party of Jim Crow and the party of opposition," Trump said, drawing boos from the supportive crowd, which was heavily white.
Trump read from prepared remarks, a new tactic he has tried more frequently in recent weeks as he has sought to steady a campaign that has long struggled to stay on message. In his prepared script, "oppression" appeared where he said "opposition."
While Southern Democrats largely pushed to protect the ability to own slaves in the 19th century and Democrats were key to the implementation of segregation laws, the nation's political parties have changed dramatically since.
Trump argued that many Africans Americans have been left behind and are suffering the effects of poverty, drugs and violence in inner cities. Democrats have criticized such comments and argued that they are insulting.
"Tonight, I am asking for the vote of every African American and Hispanic citizen in this country who wants to see a better future," Trump said.
Trump said no group has suffered more under Clinton's policies than African Americans.
Trump also said Clinton "bleache," and "used chemicals" to cover up some of her emails, an apparent reference to the emails she deleted from the personal server she used as secretary of state, saying they were private, personal notes.
Trump also raised money when he was in Everett. Many political observers questioned his decision to hold a rally in a safe Democratic state that has shown no signs of a Trump upset. Nevertheless, Trump predicted victory.
"We are going to work very hard over the next 70 days, and we're going to win this state," he declared.
