Joe Rogan, the most listened-to podcaster in the country, has issued a warning to GOP President-elect Donald Trump. Rogan, who backed Trump in the closing days of the campaign, said that the president-elect should refrain from attacking his detractors on the left and should focus on uniting the country, the Daily Mail reported.

The podcaster revealed that he watched returns come in with fellow comedian Tony Hinchcliffe, who was thrilled to see Trump’s support from Puerto Rican voters go up.
