Jim Carrey says his cartoons ridiculing the Trump administration are a civilised response to what he calls an unfolding nightmare.

The actor told a TV critics’ meeting that his sketches may veer into crassness but are a creative way to express his political opposition.

He stars in the new series Kidding, on US television network Showtime, about a children’s TV host hit by a family tragedy, which debuts on September 9.

Those who have been given the Carrey cartoon treatment include President Donald Trump and White House press secretary Sarah Huckabee Sanders.

Carrey’s sketch of Sanders was blasted as sexist and bigoted by her father, former Arkansas governor Mike Huckabee.

Some critics called it ugly, but Carrey says he did not use the word and drew Sanders’ essence.
