WATCH: D’Souza, MTG discuss abhorrent treatment of Jan 6 detainees

The situation exacerbated when building staff locked out the group of visiting GOP politicians. Rep. Marjorie Taylor Greene of Georgia, Rep. Matt Gaetz of Florida, Rep. Paul Gosar of Arizona, and Rep. Louie Gohmert of Texas were then stuck outside with a posse of accompanying press reporters.

On the latest episode of The Dinesh D'Souza Podcast, conservative commentator Dinesh D'Souza interviews Greene about the matter to learn more. Greene's memory is fresh since the discussion happened the following day.

Greene says there's ongoing questions being probed when it comes to Jan. 6 and the response from officials that day. Two days before last week's lock out at the correctional facility, the Biden administration's Department of Justice did a similar gesture by not even allowing the group into the lobby.

"As members of Congress we have oversight over the prison," she stresses.

In general terms, Greene explains that the legislative group's job in Washington includes funding the prison and making legislation that involves the facility and federal prisons all across the country. Greene adds that the group's members are on Judiciary and Oversight Committees which have "direct oversight" over these prisons and the Department of Justice.

"We went because we heard horror stories [...] about the treatment of these defendants, the Jan. 6. defendants, who have been arrested, they've been charged, and they are waiting for their court date. And some of them are not being allowed bail. We heard stories about solitary confinement, we've heard stories of beatings," she states. To tour a facility and check the conditions is something that Greene says she recently did at a California migration facility a few weeks prior.

The visit is brought up as a point of comparison. The Republican lawmaker explains how the federal government treats illegal migrants who committed crimes or are awaiting to have amnesty claims processed.

Greene says the building was "beautiful" and "immaculate" in terms of upkeep with legal resources and a library on hand to use. "They can talk to their attorneys any time they want. They can go outside, 24 hours a day. They have beautiful shower facilities, laundry facilities. They have a gym. They have a full-size basketball court and there's iPads available so they can Facetime with family...."

It's this overall normalcy of transparency elsewhere that set up expectations for the DC facility. From the minute the group of four representatives walked in the door, Greene says, what stood in contrast was the "filthy dirty" lobby.

"It was disorganized. It was not well kept," Greene describes.

Greene says the attitude of the facility staff was a worse matter. Their described behavior of arrogance and defiance made it come off like the building staffers had more authority than the politicians who approve the very funding of it. she says.

She recalls walking up to the woman stationed at the front desk and trying to put on the best friendly greeting she could. Despite calling in advance to let the staff know they were coming to inquire about Jan. 6 detainees, the woman accused that the group of elected officials were trespassing, Greene says.

Someone there said the supervisor was back outside. So she and the others went back outside, and it was then they were locked out, Greene states.

D'Souza brings up the situation in Cuba with political prisoners. He asks Greene about similarities of "authoritarian habits" at play here in the United States. Greene agreed with D'Souza, but made it clear her focus was America first.
