Trump claims he wants to testify at his trial. No one else thinks he should.

On the eve of his criminal trial, Donald Trump told reporters in Florida that he would take the stand and testify if necessary. “All I can do is tell the truth,” Trump proclaimed.

That boast is about to be put to the test, as Trump and his defense team decide in the coming days whether to present him as a witness.

But among legal experts and even Trump’s political allies, there’s already a unanimous verdict: He would be a fool to testify.
