Democrats will win control of the House, a triumph that gives the party real levers of power to check President Donald Trump and Senate Republicans, NBC News projects. The party leveraged voter enthusiasm and staggering fundraising to tip the balance of power in the chamber. As of 5:20 a.m. ET Wednesday, Democrats had gained a net 28 seats in the chamber, NBC said. They needed to flip 23 GOP-held seats to take over. The victory will put Democrats in control of the House for the first time since 2010 and likely return House Minority Leader Nancy Pelosi to the office of speaker.

The election landscape diverged as Democrats defended several Senate seats in deep red territory. Democrats picked up House districts in states such as Pennsylvania, New Jersey, Virginia, Michigan and Kansas on their way to a projected majority.

"Tomorrow will be a new day in America," Pelosi said in a speech declaring victory late Tuesday night. "Today is more than about Democrats and Republicans. It's about restoring the Constitution's checks and balances to the Trump administration." Despite his party's expected loss of House control, Trump tweeted late Tuesday touting what he called "tremendous success" in the elections. He added: "Thank you to all!" Trump tweet The expensive and bitter midterm victory will have widespread implications for Trump and the lawmakers in his Republican Party. Democrats will now have the ability to launch investigations into the president and his Cabinet members. They appear poised to go after the president's elusive tax returns. They also could pass legislation aimed at protecting special counsel Robert Mueller's probe. The party will also have the ability to check the GOP on economic issues such as taxes and health care. But the shift in power also opens the door to cooperation on reducing drug prices or improving infrastructure, the latter of which may prove as difficult as it has so far in the Trump administration. Pelosi identified both issues as priorities in her speech Tuesday night.
