Rep. Eric Swalwell, D-Calif., argued Tuesday that Republicans are looking to unfairly influence public opinion about the state of U.S. surveillance by releasing a "brainwashing" memo, without letting the public see a Democratic rebuttal.

"Once the Republicans put forward what can best be described as a brainwashing memo two weeks ago, we sought to correct the record," he said on MSNBC.

Swalwell spoke just hours after the House Intelligence Committee voted Monday to release a GOP memo that Republicans say describes abuses of federal surveillance authority. But the committee, led by Rep. Devin Nunes, R-Calif., then voted not to publicize a memo that Democrats say corrects the record.

"They voted unanimously to not allow the public to see that, and that's a shame," said Swalwell, a member of the committee.

The memo will be released unless President Trump opposes the idea by the end of the week, despite arguments from Democrats that Nunes put together the memo without ever reading the underlying data they're received.

"They essentially have put out a book review on a book that Devin Nunes himself has not even read, but they said that the book is full of lies," Swalwell said.

Meanwhile, on CNN, Rep. Chris Collins, R-N.Y., defended the Nunes memo and said Republicans are confident that Nunes is accurately summarizing the intelligence he's seen.

"Our committee has all the confidence in the world in Devin Nunes," he said.

"I wish I could tell you what's in the memo," he added. "They are not Devin Nunes' cliff notes. They investigated this for months and months. It is factual, it connects certain dots, and he's not making this up out of thin air."

Collins also accused Democrats who aren't on the committee of speaking out against the Nunes memo without having read it themselves.

"The Democrats have refused to even read the memo," he said. "So when Nancy Pelosi directs her conference to not even read the memo, and they're out there talking about what's going on, they haven't read the memo."
