Joe Biden speaks to the National Urban League (CBS/screen grab)

Democratic presidential candidate Joe Biden on Thursday said that President Donald Trump is borderline "treasonous" for stating that he would accept campaign help from a foreign government.

Speaking at the National Urban League, Biden recalled that Trump had said he believed Russian President Vladimir Putin's denials about interfering in the 2016 election.

"As if it's a joke," Biden said. "It's an assault on our democracy."

The presidential candidate revealed that he had taken a pledge to report any offers from foreign governments.

"This president said he would accept that information," Biden explained. "It is outrageous, it is un-American and it's close to treasonous."
