The witness can only testify as to what he actually knows.

More than 30 witnesses testified against him at his trial.

The defense also was not allowed to call witnesses to testify in person.

But, as other witnesses testified, they just do not want to.

Several witnesses testified to seeing a blue car with one person in it.

The witness is testifying about what someone said in the past.

Yet, the defense chose to have only one witness testify before you.

Six witnesses, including Davis, testified at trial for the defense.

Later, he could not find his hotel, which was one block away, witnesses testified.

As in the past, lay witnesses may testify to facts only.
