Washington (CNN) - Political fireworks over a little-noticed Supreme Court appeal and a separate whistleblower lawsuit had U.S. Attorney General Eric Holder and a longtime congressional adversary exchanging harsh words at a House committee hearing Wednesday.
Holder, testifying before the Republican-led House Judiciary Committee, sparred with GOP Rep. Darrell Issa of California over congressional requests for private e-mails of top Holder aide Thomas Perez, who is President Barack Obama's nominee to be Labor Secretary.
