Midterm elections live updates: Trump to deliver remarks, join tele-rallies on Monday

Speaking in Dubuque, Iowa, on Sunday, Trump repeatedly discussed Michigan's Democratic Senate candidate Abdul El-Sayed. He told the crowd that Congress would need to install a "special metal detector" for him.

Trump has repeatedly attacked El-Sayed for his Muslim faith and consistently refers to him as a "jihadist."

“We’ll have to put him through metal detectors in order to seat. He’ll be -- we’ll have 100 senators and most of them can go direct. We’re going to have to get a special metal detector for Abdul,” Trump said.

At one point, as he discussed Rep. Haley Stevens’ endorsement of Republican Mike Rogers, he implied that she won the primary contest that she, in fact, lost to El-Sayed.

“If you remember, she was going to be like 25 points down, everybody thought it was going to be a walk -- a lot of people think she won,” Trump said. He praised Stevens' endorsement on Sunday, saying, "She showed great and almost unprecedented loyalty to the great people of Michigan, and that’s another important election for us. We don’t want to have a jihadist.”

Michigan Democratic Rep. Haley Stevens and Republican Senate candidate Mike Rogers, in a joint press conference after Stevens endorsed Rogers, defended the decision as one that is right for Michigan, adding that it was about standing "with country."

Stevens endorsed Rogers against Democratic nominee Dr. Abdul El-Sayed after Stevens had previously said she would support El-Sayed.

Stevens said that “90% of the votes I'm going to cast are going to be for Democrats. My vote for Senate, I am just one vote, as is every Michigander. My vote for Senate is going to be with Mike Rogers. And I will tell you why. Because we have to stand with country."

She said El-Sayed boxed her out of his campaign. "I did endorse the Democratic nominee, and he chose to close his campaign by saying I wasn't welcome… This is about looking in the mirror about how real Democrats for Rogers are."

President Donald Trump lavished praise on Democratic Rep. Haley Stevens of Michigan after she endorsed Republican Mike Rogers on Sunday over Democrat Abdul El-Sayed in the Senate race, who defeated Stevens in the primary.

“Wow, this is BIG!” Trump wrote on social media Sunday, reacting to the news.

“Her following is huge, and the level of respect from the People of Michigan, especially our African American and Jewish populations, is virtually unparalleled. Haley said what few people are willing to say,” Trump further said, adding that Stevens showed “great and almost unprecedented loyalty” to Michigan.

“It’s a thing called bravery, and few people have it like just displayed by Congresswoman Haley Stevens!” Trump said.

A federal judge on Sunday dismissed the Justice Department’s lawsuit seeking to block certification of the election in Alaska if the Democratic candidate for U.S. Senate wins, dealing yet another setback to the Trump administration as it seeks to impose itself on state-run elections just days before the midterm elections.

The Justice Department filed the extraordinary lawsuit last week at the behest of President Donald Trump. Federal prosecutors requested a delay in the certification of the outcome to allow time to investigate whether confusion over two candidates with the same name, Dan Sullivan, could effect election results.

U.S. Judge Sharon Gleason wrote in part that the Justice Department’s suit fails on the law, but also on the practicality of the request.

“The United States provides no workable plan as to how it proposes to segregate ballots cast for Daniel J. Sullivan on Election Day and then conduct a court-ordered unspecified 'investigation’ of those ballots in a manner that would preserve voter secrecy,” Gleason wrote, referring to the Democratic candidate.

The Justice Department told ABC News in a statement that it plans to appeal the ruling.
