Rep. Elijah Cummings, the powerful House Democrat who represented Baltimore for more than two decades and was a vocal critic of President Trump, died early Thursday after battling health problems, his office said in a statement. Cummings, who was 68, died at Gilchrist Hospice Care, a Johns Hopkins affiliate. As chairman of the House Oversight and Reform Committee, he was one of the most powerful Democrats in Washington, and played a key role in the House Democrats' ongoing efforts to impeach Trump.
