A legal analyst was stunned on Sunday as she discussed the Department of Justice's latest "cover-up" attempts in a case against a member of Congress.

President Donald Trump's Department of Justice has been pursuing charges against Rep. LaMonica McIver (D-NJ) for allegedly assaulting a federal officer during a protest outside of an immigration facility in Newark, New Jersey, in May. Recently, the DOJ was forced to turn over text messages to McIver's defense team that show DOJ officials knew McIver did not assault the officer, and said the video the Trump administration relied on for the prosecution did not show her assaulting the officer either.

Legal analyst Allison Gill discussed the development on the latest episode of her podcast, "The Breakdown."

"The Department of Justice is always trying to cover up the truth, and it always comes back to bite them in the a--," Gill said.

McIver was arrested during a protest against Trump's deportation policies in Newark, New Jersey, in May, when she and other Congressional lawmakers attempted to prevent Newark Mayor Ras Baraka, a Democrat, from being arrested by federal agents, the New Jersey Monitor reported.

McIver's legal team has claimed that the video of the incident would she the Congresswoman did not impede the agents, as the charging document alleges.

Gill described the DOJ withholding that evidence as a "case killer."

"You don't have to be a lawyer to understand the implications of withholding exculpatory evidence ... And even if they don't get in trouble for that, it's certainly a case killer, along with the actual video of what happened," Gill said. "All you've got to do is see it with your own eyes."
