Reacting to former special counsel Robert Mueller’s disclosure Wednesday that Russian interference in US elections continue to this day, Democratic presidential candidate Joe Biden promised he would ensure Russia’s meddling would be met with consequences if he is elected next year.

In his all-day testimony before the House Intelligence and Judiciary committees, Mueller was clear that not only did Russia interfere in the 2016 presidential election, but that interference extends to today and would continue to the 2020 election.

“I promise you — one of the things I was deeply involved with as vice president, the president [Obama] gave me a lot of room and authority in terms of foreign policy and national security — I promise you they will pay a price for continuing this proposition,” Biden said Thursday.

The former vice president also used extremely harsh language to criticize incumbent president Donald Trump, for Trump’s suggestion that he would continue to consider foreign aid to help win the coming election.

“If, in fact, I find out anything at all that is going on in terms of trying to [indecipherable] the election, whether it’s helping me or not helping me, I will immediately go to the intelligence community and the FBI,” Biden said. “This president said he’d accept that information. It is outrageous, It is un-American and it’s close to treasonous.”
