U.S. Republicans may add a leading ally of President Donald Trump to the House Intelligence Committee, Rep. Jim Jordan, to strengthen their defenses as the impeachment investigation against the president goes public.

An aide to House Republican Leader Kevin McCarthy confirmed a report by CBS News that McCarthy was eyeing making temporary adjustments to the Republican membership of the Democratic Party-led intelligence panel, which will begin holding public impeachment hearings next week.

Jordan, an argumentative former assistant college wrestling coach and former leader of the conservative House Freedom Caucus, has proven himself adept at the public defense of Trump throughout the first part of the inquiry.
