WATCH: Booker says effort to question Kavanaugh on race hampered by GOP

A Senate Democrat says his effort to question Supreme Court nominee Brett Kavanaugh about race has been hampered by Republicans’ decision to keep emails from the public.

WATCH: Day 2 of Brett Kavanaugh’s confirmation hearing

Sen. Cory Booker of New Jersey questioned Kavanaugh about an email from when he served as a lawyer for President George W. Bush. Booker says the email shows Kavanaugh was at least open to racial profiling by police.

But Booker says he can’t share the email with the nominee because it is among those that have been labeled “committee confidential” — available to senators, but not the public.

That prompted a complaint from Republicans. Sen. Mike Lee of Utah tells Booker he can’t “cross-examine somebody about a document you cannot see.”

Booker says the email’s subject is racial profiling and he wants it released publicly.
