MS NOW host Rachel Maddow compared the Trump administration's reported plans to construct several large-scale holding centers for deportees to the internment camps built for Japanese Americans during World War II.

During a Thursday appearance on "Jimmy Kimmel Live!," Maddow was asked about her new podcast series "Burn Order," which examines the U.S. government's 1940s executive order for Japanese American internment following the attack on Pearl Harbor.

After giving the audience a brief synopsis of her new show, the MS NOW host detailed how President Donald Trump's reported plans to build the holding centers reminded her of President Franklin D. Roosevelt's past decision to incarcerate Japanese Americans.

"So in World War II, there was a racial decree from our government that said, not just people who were immigrants from Japan and therefore Japanese citizens, but Americans born here — U.S. citizens — if they were of Japanese descent, if they had any Japanese racial lineage, they were expelled from the west coast of this country and more than 120,000 of them were locked up for years," she explained. 

"It's something that was so hard to believe, like, 10 years ago. Looking back — and now it's not as hard to believe, is it?" Kimmel said.

Maddow cited a December report from The Washington Post alleging that, according to internal ICE documents reviewed by the outlet, the Trump administration plans to build seven large-scale detention centers for deportees. The Post reported the facilities could house up to 80,000 people across seven locations.

DEMOCRATIC CONGRESSMAN CLAIMS TRUMP'S ICE IS 'PRIMARILY GOING AFTER INNOCENT PEOPLE, INCLUDING US CITIZENS'

"The Washington Post just reported on internal documents in the administration that say that they want a series of temporary relocation camps where they're going to hold people for weeks, and then they're going to send them to about 10 big warehouse-style facilities where they're going to hold up to 10,000 people at a time. That's exactly, exactly the structure they used for Japanese American incarceration during World War II," the MS NOW host asserted.

Maddow claimed that the Trump administration was stripping away the rights of citizens by "defining people as no longer protected by the U.S. Constitution."

"[The U.S. government] just said U.S. citizenship doesn't matter anymore. And I think that's something that this administration is more than flirting with at this point," she contended.

The White House did not immediately respond to Fox News Digital's request for comment.

When reached for comment by the Post, Tricia McLaughlin, a spokeswoman for the Department of Homeland Security, told the outlet that she "cannot confirm" the report and declined to answer questions about the alleged warehouse plan.

Iranian Supreme Leader Ayatollah Ali Khamenei signaled that security forces would clamp down on protesters after overnight marches through the streets as the country continues to see demonstrations.

Overnight, Iran was plunged into a nationwide internet blackout as anti-regime protests intensified. The blackout severely restricted communications across the country as demonstrations enter their second week and the death toll reportedly reaches 44. Live network data from NetBlocks showed internet traffic collapsing in the troubled nation on Thursday evening, shortly after calls circulated for mass protests at 8 p.m. local time.

Khamenei's warning about security forces came just days after President Donald Trump vowed the U.S. would intervene if peaceful Iranian protesters were met with violence at the hands of the regime.

"If Iran shots and violently kills peaceful protesters, which is their custom, the United States of America will come to their rescue. We are locked and loaded and ready to go," Trump wrote in a Truth Social post on Jan. 2.

Trump reiterated the statement during an interview with Hugh Hewitt on Thursday and said that if the regime forces were to kill protesters, "they will be hit very hard." The remark was posted on the State Department's Farsi feed.

The Iranian leader dismissed Trump's statements, saying that the U.S. president's hands were "stained with the blood of Iranians" as supporters shouted "Death to America!" in footage aired on Iranian state TV, according to The Associated Press.

IRAN REGIME CUTS NATIONWIDE INTERNET ACCESS AS PROTESTS CLAIM 44 LIVES ACROSS MAJOR CITIES

Khamenei said that Iranian protesters were "ruining their own streets to make the president of another country happy," referring to Trump.

Short videos purportedly showing protests against the regime still circulated before the blackout cut the nation from the internet and international calls, according to the AP. The outlet noted that the videos appeared to show protesters chanting against the Iranian regime around bonfires as debris littered the streets in Tehran and other areas in the country. Iranian state media claimed "terrorist agents" from the U.S. and Israel set the fires and sparked the violence, the AP reported.

Exiled Iranian Crown Prince Reza Pahlavi, whose father, Shah Mohammad Reza Pahlavi, fled Iran just before the 1979 Islamic Revolution, called for the protests on Thursday night. Pahlavi said on X that he was proud of all those who demonstrated against the regime on Thursday night.

"I am proud of each and every one of you who took over the streets across Iran on Thursday night... You saw how the massive crowds forced the repressive forces to retreat," Pahlavi said. "Those of you who were hesitant, join your fellow compatriots on Friday night."

Pahlavi encouraged protests on Friday to be even larger than the ones that took place the night before, saying it would further weaken the Islamic Republic's regime. He also expressed his faith that the people in the streets would not give up in the face of internet blackouts, assuring the protesters that the victory belonged to them.
