Trump's Wiretapping Accusation
By Calvin Trillin

Though almost no one else has shrunk
From saying that it's total bunk,
This man-child who must show he's strong
Cannot admit that he was wrong.

No matter if his facts are checked
And proven to be incorrect,
He still will tweet them all night long.
He can't admit that he was wrong.

The British say, "It's nonsense, mate."
His backers hyperventilate.
The man-child sings his same old song.
He can't admit that he was wrong.
