Biden was speaking last night at the Newseum in Washington, where he accepted an award from the Bipartistan Policy Center.
News outlets report that the Democrat didn't mention Republican President Donald Trump by name but said he was worried by the "almost drumbeat of denigration of the institutional structures that govern us."
Biden said trying to delegitimise the courts is "corrosive" and makes it impossible to compromise. And he said questioning the legitimacy of the free press is "one of the most dangerous things out there."
