'Start Here': House Dems vote on leadership, 3 Americans killed in Afghanistan and Trump threatens GM. What you need to know to start your day.

House Democrats vote on leadership as Senate Republicans hold on in Mississippi.

It's Wednesday, Nov. 28, 2018. Thanks for choosing to start here.

1. Hyde-Smith wins in Mississippi as Democrats vote on House leadership

Last night in Mississippi, Republican Cindy Hyde-Smith won her senate runoff race to become the 53rd Republican in the upcoming Senate.

In the House, Democrats flipped 39 seats in the midterms and could add another when the final votes in California's 21st District are counted.

That would give the Dems an even bigger cushion on House votes beginning next year.

ABC News Senior Congressional Correspondent Mary Bruce says Nancy Pelosi has been successfully whipping votes ahead of the Democrats' leadership vote today.

2. Trump threatens to pull GM subsidies after company plans layoffs

Earlier this week, when General Motors announced plans to lay off 14,000 workers and shut down five plants, it was seen as a drastic left turn by CEO Mary Barra.

President Donald Trump was among the first to push back, and yesterday he was even more explicit.

On Twitter, he reminded GM of the auto bailout in 2008 and wrote, "We are now looking at cutting all GM subsidies, including for electric cars."

ABC News Chief Business and Economics Correspondent Rebecca Jarvis tells us subsidies usually do not revolve around individual companies, and such a plan would require congressional support.

3. Americans die in Afghanistan

Yesterday was the deadliest day of 2018 for Americans serving in Afghanistan.

Three soldiers were killed, and three others were injured, when their vehicle was struck by an IED.

ABC News Senior Foreign Correspondent Ian Pannell tells us that the view from the ground contradicts any messages of progress and peace.
