A Republican victory in both chambers of Congress would be a validation for Mr Trump's polarising style, a month after he solidified a conservative majority on the Supreme Court when the Senate confirmed his nominee Brett Kavanaugh after a fight over sexual misconduct accusations against the jurist.
The Democratic victory, she said, "is about restoring the Constitution's checks and balances to the Trump administration", and a check on Senate Republicans.
In the suburbs outside the nation's capital, Virginia Rep. Barbara Comstock - among the most endangered GOP incumbents, branded Barbara "Trumpstock" by Democrats - lost to Jennifer Wexton, a prosecutor and state legislator.
But in some other toss-up races, the GOP managed to hold on. Democratic favorite Conor Lamb, who stunned Washington by winning a special election in the state, beat Republican Rep. Keith Rothfus in a new district. She finished about 3 percentage points behind the incumbent in a Lexington-area district Trump won by 15 percentage points in 2016.
Outside Richmond, Virginia, one-time tea party favorite Rep. Dave Brat faced an unusually strong challenge from Democrat Abigail Spanberger, a former Central Intelligence Agency operative motivated to run for office after the GOP vote to gut the Affordable Care Act. Analysts expect pressure on stocks if Democrats gain control of the House and a sharper downward reaction if they win the Senate, too. The flood of political donations from interest groups and individuals will make it the most expensive midterm ever, and early signs suggest voter turnout could be the highest in half a century.
Trump called Senate Majority Leader Mitch McConnell, R-Ky., "to congratulate him on the historic Senate gains", White House spokeswoman Sarah Sanders said.
In the Senate, which is made up of 100 seats, 35 seats are up for election. AP VoteCast also showed a majority of voters considered Trump a factor in their votes.
Colorado father pleads guilty allowing him to avoid the death penalty
According to court documents, a police investigation determined that Watts "was actively involved in an affair with a co-worker". The agreement also required Watts to plead guilty to unlawful termination of Shanann Watts' pregnancy, a felony in Colorado.
Polls are also closed in parts of in, where Democrat Joe Donnelly, a top target of the President's frenetic final midterm election campaign swing, is fighting an uphill battle for re-election against Republican Mike Braun.
Around 37 percent of eligible voters took part in the 2014 mid-term elections, down from 42 percent in 2010. That could help Democrats because younger voters tend to lean their way.
Trump spent the day at the White House, tweeting, making calls, monitoring the races and meeting with his political team.
In the final days of the campaign, Trump amped up his rhetoric, peppering his rallies with improbable doomsday scenarios should the Democrats win control of one or both congressional bodies. "This is a referendum on the party in power".
The Democrats are favoured by election forecasters to pick up the 23 seats they need to gain a majority in the House, but opinion polls show they have slimmer hopes of picking up the two seats they need to gain control of the Senate.
A loss of the House will also trigger significant second guessing of the President's tactics, given that he chose not to make the booming economy his primary midterm argument, instead turning to a searing indictment of Democrats focusing on immigration and laden with racial language. A slow-moving caravan of thousands of Central American migrants trekking to the U.S. has served as ready fodder for Trump's diatribes for border security and immigration reform, and a roaring economy has helped the GOP foster confidence in their leadership.
"We're going to win, based on data", Pelosi of California said at the Democratic campaign headquarters in Washington. Tammy Baldwin held off a challenge from Republican Leah Vukmir, but her fellow Democrats Heidi Heitkamp of North Dakota and Claire McCaskill of Missouri were defeated by their Republican opponents.
Milan Pavkov's Brilliant Long Range Shot Gives Red Star 2-0 Lead
Four points from their last two games would be enough to guarantee the Reds' progress to the last 16. Red Star scored on 50 percent of its shots on frame, finishing with four shots on goal.
Democrats' performance in the House battlefield was mixed.
The most important elections concern Congress as it is the national legislative body responsible for passing laws on everything from immigration to the economy. "It's just a very robust class of candidates that really reflects who we are as a country".
Fifty-eight of voters said the country is headed in the wrong direction, compared with 41 percent who said it is on the right track, according to a nationwide survey conducted in all 50 states for The Associated Press and Fox News. The survey is separate from the traditional exit polls for the television networks.
Republicans have retained Senate control for two more years. He said since Trump has been president, he 's hired two more employees for his six-person company.
Organiser Suhaib al-Hanooti said the turnout in Dearborn's Arab American community was "phenomenal" on Tuesday.
"But we won't just vote against radicalism, bigotry and corruption today", she said. Besides the House and Senate races, there are two contests for governor which are drawing particular attention.
The campaign will be the most expensive midterm in history, projected by the nonpartisan Center for Responsive Politics to exceed $5 billion. Other records were also falling. At least 255 women were on the ballot as major party congressional candidates.
