Rep. Elijah Cummings (D-Md.) has died, according to a statement from his office.

The Democratic member of Congress, who chaired the House Oversight Committee, which was among the panels investigating the impeachment of President Donald Trump, was 68. 

Cummings died at Gilchrist Hospice Care, an affiliate of Johns Hopkins Hospital in Baltimore at approximately 2:30 a.m. Thursday morning “due to complications concerning longstanding health challenges,” his office confirmed in a statement to HuffPost.

Cummings, the son of a sharecropper, practiced law for almost two decades and served in the Maryland House of Delegates before winning his congressional seat in 1996, where he was renowned for championing civil rights issues.

His House committee’s probes into the Trump administration drew fierce anger from the president. In July, Trump tweeted racist insults about Cummings and his majority-black district, calling it a “rodent-infested mess.”

Cummings earlier this year said he had “no doubt” that Trump is a racist after the president said four Democratic members of Congress ― all women of color ― should “go back” to other countries.

On the only time in 2017 that Cummings talked one-on-one with Trump about lowering drug prices, the Baltimore Sun reported him as telling the president: “Mr. President. You’re now 70-something, I’m 60-something. Very soon you and I will be dancing with the angels. The thing that you and I need to do is figure out what we can do — what present can we bring to generations unborn?”

The Baltimore archdiocese tweeted this tribute to Cummings:
