Alan Dershowitz said it was "perfectly lawful" for Rep. Adam Schiff's staffers to meet with Michael Cohen before the former Trump attorney's high-profile public testimony.

Citing two sources familiar with the matter, reported that members of Schiff's (D-Calif.) staff traveled to New York at least four times to meet with Cohen for more than 10 hours.

Some Republican lawmakers have questioned whether the meetings amounted to coaching a witness, and Rep. Mike Turner (R-Ohio) called out the fact that Democratic staff "traveled on taxpayers' dime" for the Cohen meetings.

On "America's Newsroom" Friday, Dershowitz said he doesn't understand what all the fuss is about, as congressional staffers often travel to prepare witnesses.

"It really depends what influence the lawyers or staffers may have had on his testimony," Dershowitz said. "They're not allowed to tell him what to say, obviously. On the other hand, they're allowed to suggest what the areas of interest are of the members of Congress."

He pointed out that if Republican lawmakers were preparing for a hearing with someone testifying against Democrats, they also would send their staff to speak to the individual beforehand.

He said these meetings between Cohen and Schiff's staff should be looked into "very carefully," but with the presumption of innocence.

"This sounds like a lot of sound and fury signifying nothing," Dershowitz said, paraphrasing a line in William Shakespeare's Macbeth.
