The victories are sure to reinforce the mandate of a president who nationalized the midterm elections by rallying his supporters to vote for Republicans as though his "America First" agenda was on the ballot.
"Now is the time for members of both parties to join together, put partisanship aside, and keep the American economic miracle going strong", Trump said.
In Minnesota, Omar, a 36-year-old naturalized American citizen and state representative, campaigned on policies embraced by the Democratic Party's most liberal wing: universal health care, free college tuition and robust public housing. Lindsey Graham, who led an effort to impeach President Bill Clinton, warned his Democratic colleagues of the perils of that approach.
He said: "I'm proud of what happened".
"The Trump thing works", says GOP pollster Frank Luntz.
"Mia Love gave me no love", the president said.
Democratic leaders plan to satisfy those demands by using their newfound majority to push through long-stalled initiatives that they say have broad support within the electorate.
Trump reeled off a shopping list of disadvantages he claimed that the Republicans had faced going into Tuesday's vote, including "wealthy donors and special interests" for the Democrats, and "very hostile media coverage".
Democrats stormed to victory in the House, powered by a disparate coalition of young people, minorities, women, and suburban white voters who mobilized in opposition to the president. "CNN should be ashamed of itself having you working for them".
"You are a rude, awful person", Trump told Acosta.
Trump also called out Republicans who did not accept his offer of campaign help, saying they failed to accept his "embrace".
The Democrats gained more than the 23 seats they needed for a majority in the 435-seat House of Representatives. The lead story in National Review was "Republicans Hold the Senate", though that rather predictable outcome is less important than Dems flipping the House.

But the olive branch he extended was studded with thorns as he declared that he would retaliate if Democrats use their control of the House to issue subpoenas to seek his tax returns and investigate his business dealings, his Cabinet's conduct and his campaign's ties to Russian Federation, as expected.
While Trump retains broad power over national security and United States foreign policy, the midterm election result exposes him to congressional investigations that could reverberate beyond American borders. "And if it becomes clear that this is another move to shut down the Mueller investigation, then that is something that we'll have to seriously consider". This will include a review of the heretofore elusive Trump corporate and individual income tax returns. The two houses of Congress write the laws, and the president enforces them.
When asked where he could specifically find common ground with House Democratic Leader Nancy Pelosi, McConnell struggled to name examples - offering only the usual example of infrastructure, something that is often cited but rarely a bipartisan achievement.
"Maybe we will make a deal, maybe we won't".
Trump briefly sought to strike a statesmanlike tone in his first public remarks after the loss, praising House Democratic leader Nancy Pelosi for her hard work and envisioning "a handsome, bipartisan type of situation" on infrastructure investments and health care.
Almost 40% of voters cast their ballots to express opposition to the president, according to VoteCast, while one-in-four said they voted to express support for Trump.
Like in the 2016 presidential election, rural areas went heavily for Republicans on Tuesday while urban areas broke towards the Democrats. That echoed a similar message from Trump, who on Twitter cautioned Democrats not to use their new House majority to launch investigations into his administration.
