Nov. 6 (UPI) -- The Democratic Party was projected to take control of the House while Republicans maintain control of the Senate in Tuesday's midterm elections.
Democrats secured more than a dozen seats and were expected to pick up more than needed to have a majority in the lower chamber, NBC News and CNN projected.
House Democratic leader Nancy Pelosi said Tuesday's vote restored represented a "new day in America." She promised accountability and bipartisanship in the Democratic-led House.
"Today is more than about Democrats and Republicans," she told a crowd of supporters. "It's about restoring the Constitution's checks and balances to the Trump administration."
Democrats picked up key seats with wins from Donna Shalala and Debbie Mucarsel-Powell in Florida; Colin Allred in Texas; Jennifer Wexton and Elaine Luria in Virginia; Haley Stevens in Michigan; Jason Crow in Colorado; Mikie Sherrill in New Jersey; Sharice Davids in Kansas; Dean Phillips in Minnesota; Max Rose and Antonio Delgado in New York; and Conor Lamb, Chrissy Houlahan, Susan Wild and Mary Gay Scanlon in Pennsylvania.
With 16 percent of the vote counted, Stevens had a double-digit lead over her competitor, Lena Epstein. Stevens will become one of only a few Democrats to represent Michigan's 11th District over the past 135 years.
In Texas, former NFL player Allred ousted Rep. Pete Sessions, who has served in the House since 1997.
"This victory would not have been made possible without you. This people-powered campaign has made history tonight and North Texans made their voice heard. Now the real work begins," Allred wrote on Twitter.
Republicans picked up a House seat in Pennsylvania with Guy Reschenthaler.
Another tossup district, Kentucky's 6th, went to Republicans. NPR and Bloomberg projected the race for incumbent Rep. Andy Barr over challenger Amy McGrath.
In the Senate, Republican challenger Mike Braun unseated Sen. Joe Donnelly in Indiana and Republican Rep. Kevin Cramer beat Sen. Heidi Heitkamp, ending Democrats' hopes of turning the chamber blue.
"Serving the state that has given me so much will be the honor of my life, and Maureen [and] I are thrilled to begin this next chapter of our American story," Braun said in a statement.
CNN and ABC News also projected a win for GOP Sen. Ted Cruz, who faced stiff competition from Democratic challenger Rep. Beto O'Rourke.
President Donald Trump called Election Day a "tremendous success" on Twitter.
Heading into Election Day, Republicans controlled the Senate with 51 seats to Democrats' 49. The latter needed to pick up two seats to hope for control.
Sens. Bernie Sanders, I-Vt., Tim Kaine, D-Va., Joe Manchin, D-W.Va., Amy Klobuchar, D-Minn., Martin Heinrich, D-N.M., Bob Casey, D-Pa., Kirsten Gillibrand, D-N.Y., Tammy Baldwin, D-Wis., Sen. Elizabeth Warren, D-Mass., and Sherrod Brown, D-Ohio, secured re-election.
Republican Marsha Blackburn won the Senate seat left open by retiring Sen. Bob Corker. She becomes the state's first female senator.
Mississippi's Senate race will head to a runoff after no candidate reached the minimum 51 percent of votes. Republican incumbent Sen. Cindy Hyde-Smith will face Democratic challenger Mike Espy on Nov. 27.
Meanwhile, former Massachusetts Gov. Mitt Romney returns to politics, this time representing Utah in the Senate. He defeated Democrat Jenny Wilson to replace retiring Sen. Orrin Hatch, a Republican.
The Indiana Senate race was one of about eight Senate races considered to be tossups, including Democrat-held seats in Florida, Missouri, Montana and West Virginia, and Republican-held seats in Arizona, Nevada and Tennessee.
In Montana, Democratic incumbent Jon Tester was in a tight race to keep his seat against Republican challenger Matt Rosendale. With Trump's help, Rosendale has closed the gap on Tester, who had led the race by 9 points in a poll last month (47-38).
Other congressional wins of note include:
-- Democrat Alexandria Ocasio-Cortez, whose win in New York's 14th District makes her the youngest woman elected to Congress.
-- Democrats Ilhan Omar of Minnesota and Rashida Tlaib of Michigan, who will become the first Muslim women elected to Congress.
-- Democrat Ayanna Pressley, who will be Massachusetts' first African-American woman in the House.
-- Democrats Veronica Escobar and Sylvia Garcia, who will become the first Latinas elected to Congress from Texas.
-- Republican Greg Pence, who will be the first brother of a vice president -- Mike Pence -- elected to the House.
