U.S. Secretary of State John Kerry on Tuesday warned of the dangers of authoritarian populism and offered a thinly veiled critique of Donald Trump¡¯s prolific use of Twitter, saying it allowed the president-elect to avoid accountability.

In his most pointed public comments about Trump since the Nov. 8 presidential election, Kerry also suggested that the president-elect¡¯s Cabinet nominees were getting a free pass from Congress for failing to submit tax returns and other documentation before their Senate confirmation hearings.

¡°Every country in the world better ... start worrying about authoritarian populism and the absence of substance in our dialogue,¡± Kerry told a Washington forum.
