The feds don’t want any witnesses at the trial of reputed drug lord Joaquin “El Chapo” Guzman to be asked about President Trump’s statements on “flippers,’’ or government informants, Brooklyn court papers show.

The case against Guzman will include testimony from informants, and Trump’s comments could be seen as prejudicial, according to a motion filed by US Attorney Richard Donoghue’s office Friday.

Last month, after Trump’s former lawyer Michael Cohen took a plea deal, the president called his actions “flipping. And it almost ought to be illegal.’’

El Chapo’s lawyer, Jeffrey Lichtman, said he didn’t have a problem steering clear of Trump’s comments, although “that doesn’t mean we aren’t going to bring out the fact that cooperating witnesses have a huge incentive to curry favor with the government.”
