In pushing back against damaging new claims by former White House adviser Omarosa Manigault Newman, the Trump administration confirmed reports that President Trump had White House staffers sign nondisclosure agreement (NDAs). On Sunday, White House counselor Kellyanne Conway told ABC News that NDAs are "typical" in offices and "we've all signed them in the West Wing," and Trump tweeted Monday: "Wacky Omarosa already has a fully signed Non-Disclosure Agreement!" This raises a lot of questions. Here are five:

1. What does the White House NDA say? Several Trump aides told The Washington Post it prohibits sharing any confidential or nonpublic information outside of the White House at any time. It specifically "prohibited top aides from disclosing confidential information in any form including books, without the express permission of the president," a former administration official tells Politico. And violators "would have to forfeit to the U.S. government any royalties, advances, or book earnings."

2. Are these NDAs enforceable? Most legal experts say no, because muzzling government employees would violate the First Amendment. Also, public employees "are supposed to serve the public and the institution of the president, not any one particular person," Politico explains.

3. Did Manigault Newman sign one? She says she refused. She did, however, apparently sign a stricter NDA to work on the Trump campaign and, according to The Daily Mail, the Trump 2020 campaign plans to sue her for breach of that agreement.

4. So which White House employees did? Conway suggests she was one of the "dozens of seniors aides" who signed the NDA, some after being told it was unenforceable, The Washington Post reports. Still, any officials who did sign away the right to say anything negative about Trump for years or forever "probably shouldn't be given a platform — on, say, a cable news channel — to opine about Trump," notes The Weekly Standard's Jonathan Last, "because you're not allowed to say what you really think."

5. If the NDA is toothless, does it matter? Yes, Last argues, because "the purpose of an NDA isn't to be enforced — it's to obstruct the revelation of information by making such revelations costly." Peter Weber

Rep. Marcia Fudge (D-Ohio) announced on Tuesday she will not challenge Rep. Nancy Pelosi (D-Calif.) for the role of speaker of the House and is offering her endorsement.

"I now join my colleagues in support of the leadership team of Pelosi, [Rep. Steny] Hoyer, and [Rep. James] Clyburn," she said in a statement. Pelosi, Hoyer, and Clyburn are the three highest-ranking Democrats.

Fudge said she was concerned about "voter protection and voter integrity," and the Democratic Party "should reflect the diversity of our changing nation and guarantee all our citizens the unfettered right to vote and to have every vote count." Pelosi, she said, has "assured me that the most loyal voting bloc in the Democratic Party, black women, will have a seat at the decision-making table" and "protections of the Voting Rights Act will be reinstated and improved."

Last week, 16 Democrats signed a letter saying they will oppose Pelosi for speaker. So far, no challengers have emerged, with House Democrats set to vote to select a nominee next week. Catherine Garcia

President Trump has given Special Counsel Robert Mueller written responses to questions asked about Russian meddling in the 2016 presidential election, Trump's lawyers said Tuesday.

Attorney Jay Sekulow said copies of the questions and Trump's answers, as well as correspondence between Trump's legal team and Mueller's office, will not be released to the public. Another attorney, Rudy Giuliani, said it is now "time to bring this inquiry to a conclusion." This is the first time Trump has directly cooperated with the probe, The Associated Press reports.

It took about a year for Mueller's office and Trump's attorneys to reach the compromise of Trump answering Russia-related questions without having to appear for a sit-down interview. Part of the compromise included Mueller setting aside for the time being questions about obstruction of justice in relation to the firing of former FBI Director James Comey, AP reports.

The Department of Homeland Security is paying undercover informants inside the migrant caravan headed to the southern border, two DHS officials told NBC News on Tuesday.

There are about 4,000 migrants in the caravan, most of them from Central America, and to communicate, they are using WhatsApp to text. DHS personnel are monitoring those messages, the officials said, as well as working with the Mexican government to keep track of the size of the caravan and any possible security threats.

On Monday, DHS announced that on Sunday night, it had gathered intelligence indicating that some migrants planned on running through the lanes at the border crossing near San Diego. The northbound lanes were closed for three hours, and no migrants attempted to rush through.

It's not known how much the Department of Homeland Security is spending on the informants. In a statement, DHS spokeswoman Katie Waldman told NBC News the department has "an obligation to ensure we know who is crossing our borders, to protect against threats to the homeland, and any indication to the contrary is misinformed."

Former White House Counsel Don McGahn apparently had a very hard time convincing President Trump to leave Hillary Clinton and James Comey alone.

This spring, Trump told McGahn he "wanted to order the Justice Department to prosecute" the former secretary of state and former FBI director, two sources tell The New York Times. McGahn immediately shut the president down, reportedly saying he didn't have the power to order a prosecution. Trump could try investigating his political rivals, McGahn said, but that could "prompt accusations of abuse of power" and potential impeachment charges, the Times writes. McGahn then reportedly made White House lawyers wrap up all that advice in an official memo.

But McGahn's words didn't seem to sink in. Trump has "continued to privately discuss the matter, including the possible appointment of a second special counsel" to investigate Comey and Clinton, the Times writes. The president had also reportedly hoped his FBI Director Chris Wray would take action against Clinton, but Wray let him down.

It's unclear what Trump exactly would like to prosecute Comey and Clinton for. But the matter displays how Trump "views the typically independent Justice Department as a tool to be wielded against his political enemies," the Times writes — something that could become particularly relevant with the appointment of loyalist Matt Whitaker as acting attorney general.

The White House declined to comment to the Times. McGahn's lawyer would not comment on any legal advice relayed to the president, but said to McGahn's knowledge, "the president never ... ordered that anyone prosecute" Clinton or Comey. Read more at The New York Times. Kathryn Krawczyk

Mississippi Sen. Cindy Hyde-Smith (R) may have lost Walmart's support over a so-called joke about lynching. But President Trump is still firmly on her side.

Trump has already scheduled two campaign rallies for the Republican, whose previously easy race in a runoff election against Democrat Mike Espy has started looking tighter. And on Tuesday, Trump called Hyde-Smith "spectacular" and suggested he'd hold three rallies for her if he could — just after Politico dug up some photos of her in a confederate soldier's hat.

Hyde-Smith first walked into trouble last week after a video showed her saying that if a supporter "invited me to a public hanging, I'd be on the front row." Espy's campaign called her comments "reprehensible," but Hyde-Smith said they were taken out of context. Another video captured her suggesting voter suppression was "a great idea" in what her campaign said was a joke.

After the first round of dust had settled, a photo of Hyde-Smith in a Confederate soldier's hat and toting a musket surfaced. The photo came from Hyde-Smith's public Facebook post of her time at the Jefferson Davis Home and Presidential Library, a visit she described as "Mississippi history at its best!"

It's unclear if Trump saw the Confederate picture before he commented about her to reporters on Tuesday. Still, he said Hyde-Smith "feels very badly about" some unspecified comment, but added that "it was just sort of said in jest," per the Toronto Star's Daniel Dale. Kathryn Krawczyk

In very important chocolate spread news, market leader Nutella will soon be facing a serious competitor.

Barilla, an Italian company whose blue pasta boxes you probably recognize from supermarket shelves, plans to release a chocolate spread called Crema Pan di Stelle next year, reports Reuters.

The move to compete with Ferrero, the company that makes Nutella, is part of a burgeoning, delicious rivalry between the two Italian companies. The competition really began to heat up when sources said Ferrero would release a biscuit filled with Nutella in 2019, similar to Barilla's established line of cookies, Baiocchi, Reuters reports.

Barilla will try to get a spoon up on the competition by producing chocolate spread made with sunflower oil. Nutella has faced backlash for using palm oil in its recipe after the ingredient was deemed a "potential health concern," reports CNN.

Barilla's take on the chocolate and hazelnut goodness will feature a crunch, thanks to the addition of Pan di Stelle cookie crumbles, reports Reuters. Crema Pan di Stelle could launch in Italy as early as January, but industry experts say it could cost the company millions of euros to convince stores to display the new spread with the same prominence as Nutella. No word yet on when consumers in the U.S. will be able to try the new spread and help decide who should come out on top in the Italian sweet treat rivalry. Read more at Reuters. Taylor Watson
