As per 1/6/2019 NPR report, “A Guide To Who’s Who In House Leadership For The 116th Congress” by Jessica Taylor:

Excerpts:

The 116th Congress officially convened (in January 2019) with Democrats taking control of the House of Representatives for the first time in eight years.

The Democratic leadership is a diverse slate, representing the record number of women and minorities their new caucus brings to Capitol Hill — Nancy Pelosi is resuming her place as the first female House speaker in history, with four other top positions.

Here’s who you need to know in House leadership for (the Democratic Party) in the new Congress:

Democrats

Pelosi made history as the first woman speaker ever when she took the gavel in 2007. Now, she retakes it again 12 years later, also making her the first speaker to reclaim the position in more than six decades.

House Majority Leader Steny Hoyer, D-Md.

The 79-year-old Hoyer also resumed the same post he had during Democrats’ last turn in the majority, moving up from serving as minority whip for the past eight years.

Pelosi and Hoyer have a had a long, sometimes testy, relationship. She hails from the legendary Maryland D’Alesandro political family, but that hasn’t always endeared the two to each other, though they’ve denied any friction in recent years. Pelosi first beat Hoyer for whip in 2001 and she backed a challenger to Hoyer for majority leader when Democrats last took control in 2006.

As The New York Times, recently wrote, the “Pelosi-Hoyer frenemies dynamic, long a subject of intrigue in the Capitol, is growing ever more complex” as they’re back in power together. But Hoyer has been a political survivor. He’s the longest-serving current Democrat in the House, first elected in 1981. Hoyer is also the only white male in the top ranks of Democratic leadership.

House Majority Whip Jim Clyburn, D-S.C.

The 78-year-old Clyburn is the highest-ranking African-American lawmaker in Congress. He served as whip when Democrats had the majority from 2007 until 2011, and then served as assistant House Democratic leader while Democrats were in the minority — a post Pelosi created especially for him when Hoyer and Clyburn were competing against each other after the 2010 elections. When Democrats were last in the majority, Clyburn served as chairman of the House Democratic Caucus.

It wasn’t lost on many Democrats this year, though, that the trio at the top of the leadership ranks are all in their late seventies. And there’s a proposal Pelsoi has backed to change that, term-limiting the top three spots to bring change over the next few years.

Assistant Speaker, Ben Ray Lujan, D-N.M.

Lujan was awarded this No. 4 post after leading the Democratic Congressional Campaign Committee for the past two cycles, resulting in a 40-seat gain in November and Democrats flipping control of the chamber. The position makes the 46-year-old the highest-ranking Latino in Congress, and part of a new generation of potential Democratic leaders once the top three leaders eventually step aside.

Democratic Caucus Chairman Hakeem Jeffries, D-N.Y.

Jeffries narrowly defeated California Rep. Barbara Lee in caucus elections in November to claim the No. 5 leadership post. Some of Lee’s allies claimed sexism and ageism in the vote, and criticized Jeffries as too centrist. Still, the victory set up the 48-year-old New York lawmaker, once called “Brooklyn’s Barack Obama,” as a possible speaker of the House one day, which would make him the first black Speaker in history if that happens. And his addition means there’s another African-American in Democratic leadership.

Democratic Congressional Campaign Committee Chairwoman Cheri Bustos, D-Ill.

Bustos has the tough task of protecting Democrats’ newfound majority, but she brings credentials to the table unlike the others atop leadership — she represents a somewhat rural Illinois district that Trump narrowly carried, not unlike many of the seats Democrats will have to defend in 2020. A political protege of Senate Minority Whip Dick Durbin, D-Ill., the centrist lawmaker even got four votes for speaker from incoming moderate Democratic freshmen.

On May 29, 2019, Jim Rieger and Amber Phillips of the Washington Post penned the following report,  “More than 40 (59) House Democrats want to open an impeachment inquiry into Trump” “42 (60) representatives, including one Republican, say they support opening an impeachment inquiry into whether President Trump committed “high crimes and misdemeanors.”)
