TV networks don't exactly want to tune into President Trump's immigration ideas.

On Monday, Trump announced he'd be giving a Tuesday speech on what he called "the humanitarian and national security crisis on our southern border." But networks aren't too interested in giving up their prime time hour to air an unchallenged presidential manifesto, one TV executive tells CNN's Brian Stelter.

The government shutdown is now in its third week, and Trump still hasn't relented on his demand for $5 billion in border wall funding. He plans to make his case for the wall Tuesday at 9 p.m. EST, and requested the time slot from the four major networks: ABC, CBS, FOX, and NBC, per The New York Times. They're currently "deliberating" over whether to give it to him, a network source tells Stelter.

"Networks don't automatically say yes when a president asks for airtime," Stelter tweeted. For example, when former President Barack Obama similarly asked to air an immigration reform address in 2014, major networks said no. The Trump factor makes the decision especially difficult, as one TV executive pointed out.

Beyond the political optics, networks also worry about losing ad spots they've already sold within their prime time slots. Such lucrative 9 p.m. shows as Ellen's Game of Games would be trumped, after all. Kathryn Krawczyk

Acting Customs and Border Protection Commissioner John Sanders will leave his job next month, The New York Times reported.

Sanders has served as the agency's acting head since the previous commissioner Kevin McAleenan left to head the Department of Homeland Security in April. His departure comes as CBP faces growing criticism of its treatment of detained migrant children, though The Washington Post's Nick Miroff cites a DHS official in saying that isn't the cause of Sanders' resignation.

CBP has long faced scrutiny over its treatment of migrants at the border, especially under President Trump's administration. That ramped up last week amid reports that nearly 300 minors, some as young as 2 and half years old, were facing unsanitary conditions at a Clint, Texas detention facility. Most of them had been transferred out of the facility and to a tent camp on Monday, but on Tuesday, CBP reportedly moved 100 of those children back.

Before heading CBP, Sanders was the agency's chief operating officer and is a close ally of McAleenan. Sanders offered his resignation to McAleenan on Monday, saying it would be effective July 5, The Wall Street Journal notes. He didn't elaborate on his reasons for resigning. Kathryn Krawczyk

More than 100 migrant children have reportedly been moved back to a border station in Clint, Texas, which independent monitors described as having "unconscionable" living conditions, after they were initially moved into the care of Health and Human Services.

Clara Long, a senior researcher for Human Rights Watch, said the children at the Clint facility did not have access to soap to wash their hands and were only allowed to shower infrequently, if at all, during multiple weeks of detainment. A Customs and Border Protection official denied the allegations about the lack of crucial amenities like soap and water — which CBP says are continuously available — but did agree with the reports from the monitors that unaccompanied minors should not be living in CBP facilities. "We do not want them in our custody, our facilities are not built for that," the official said in a call with reporters on Tuesday.

CBP reportedly transferred the care of 250 migrant children held in Clint to Health and Human Services to help relieve overflow, but 100 of those children are heading back to the border station because CBP says there are no longer capacity issues, CNN reports. Tim O'Donnell

We have a new White House press secretary.

First Lady Melania Trump on Tuesday announced that her communications director, Stephanie Grisham, will take over for Sarah Huckabee Sanders as the new White House press secretary. She'll be serving dual roles in the administration, as Trump also announced that Grisham will serve as the next White House communications director, too. This job had previously been vacant.

In a tweet, Trump said she is excited for Grisham to work "for both sides" of the White House.

Grisham had been seen as a top contender to replace Sanders, with Axios having previously reported that President Trump "has told people he likes her and trusts her." Axios also noted that Grisham, who served as an aide during Trump's 2016 run, is "one of a tiny number of campaign originals left in the White House." The New York Times describes Grisham as "loyal and sometimes combative," adding that she's "known for defending Mrs. Trump and the Trump family, and for her ability to keep the East Wing relatively free of leaks." And a former senior White House official described her to CBS as "the ultimate Trump loyalist." Brendan Morrow

Rep. Duncan Hunter (R-Calif.) misused thousands of dollars of campaign funds during the course of multiple extramarital relationships, federal prosecutors said in new court filings.

Hunter was previously indicted for allegedly putting $250,000 in campaign funds to personal use, and the Justice Department now says this included funds he used to "pursue a series of intimate personal relationships" with at least five women, Politico reports.

Prosecutors said that all of these women were involved in politics in some way, and he allegedly carried out multiple affairs with lobbyists. The court filing, for instance, details a trip Hunter allegedly took with a lobbyist to Lake Tahoe, during which he put about $1,000 for his hotel bill on his campaign credit card, also using campaign funds to pay for airfare and a $7 beer, reports USA Today's Brad Heath.

The filing also describes additional alleged relationships with lobbyists, as well as a House aide, who prosecutors said he took out for drinks that he paid for using campaign funds. They said he had affairs with a woman who worked in his office as well, plus another woman who worked in the House of Representatives, The Washington Post reports.

“Carrying out all these affairs did not come cheap — Hunter spent thousands of dollars treating women to meals, drinks, and vacations, and traveling to and from their homes,” prosecutors said, The Daily Beast reports. They also said Hunter's use of campaign funds was "necessary for Hunter to satisfy his desire for intimacy" due to the Hunters' "financial difficulties."

Hunter has denied any illegal activity. His wife, who was also indicted, recently changed her plea to guilty, and prosecutors in their latest filing say that she may be called to testify. The trial is set for Sept. 10. Brendan Morrow

President Trump's cough criticism was about much more than germs.

During an ABC News interview that aired last week, Trump's insistence that his Acting Chief of Staff Mick Mulvaney "leave the room" if he was "going to cough" stole the show. It's true that Trump is a "germaphobe who does not like shaking hands or being around sick staffers," and some staffers saw the incident as a reflection of that, Politico reports. Yet other Trump allies saw it as "the public airing of Trump's newfound irritation with his acting chief," Politico continues.

Mulvaney has been Trump's top aide since John Kelly departed at the end of last year, but still hasn't lost his title's "acting" designation. Yet White House staffers insist that doesn't mean Mulvaney will be ousted soon, seeing as Trump "likes the hands-off approach Mulvaney has taken to his schedule, whims and decision-making style," Politico reports. Instead, that not-so-temporary title, along with the ongoing insults, seem to be the president's way of "assert[ing] his dominance over an ally or staffer who Trump feels has gotten too big for his britches," Politico continues.

Those pompous moves Mulvaney is allegedly making? Filling the West Wing with his former Office of Management and Budget staffers, piling his favorite aides onto Air Force One trips, and organizing three senior staff retreats to Camp David, to name a few.

Both Mick Mulvaney and outgoing White House Press Secretary Sarah Huckabee Sanders did not respond to requests for comment. Read more at Politico. Kathryn Krawczyk

Most Democratic voters want to hear less about North Korea and more about climate change in this week's Democratic primary debates, a new Morning Consult/Politico poll finds.

The Democratic voters said it was "very important" that the candidates discuss climate change, gun policy, and abortion, while U.S. tensions with Iran and North Korea, and trade issues concerning China and Mexico, take a back seat. Of those foreign policy issues, Iran leads the charge, but it still fails to reach the 50 percent threshold, coming in at 47 percent. North Korea, China, and Mexico all hovered in the thirties.

Meanwhile, climate change — which many voters want to serve as the sole topic for a single debate — led the field with 63 percent, followed by gun policy at 62, and the wave of recent restrictive abortion bills at 60.

All in all, it seems, Democratic voters don't want President Trump to take over the debate stage, at least not entirely — 44 percent of those polled said they think it's "very important" that he comes up as a topic of discussion.

The poll was conducted online between June 21-24 among a sample of 1,991 registered voters across the United States. The margin of error was two percentage points. Read more at Morning Consult. Tim O'Donnell
