Congressman Jamie Raskin of Maryland will serve as the top Democrat on the House Oversight Committee. His party voted Thursday to elect him to the role. As the ranking member on the committee, Raskin will be tasked with leading the defense against a series of planned Republican investigations into the Biden administration when the new Congress convenes in January. House Republicans have vowed to investigate everything from the Biden administration’s handling of the border and withdrawal from Afghanistan to the controversy surrounding Hunter Biden’s laptop.
