Rep. Devin Nunes on Wednesday mocked Democrats for having former special counsel Robert Mueller testify about his investigation into Russian election interference in 2016 as a “last gasp of the Russian collusion conspiracy theory.”

“They said they want to, quote, bring the Mueller report to life and create a television moment through ploys, like having Mr. Mueller recite passages from his own report. In other words, this is political theater, it’s a Hail Mary attempt to convince the American people that collusion is real and that it’s concealed in the report,” said Nunes, the ranking Republican on the House Intelligence Committee.

He likened Democrats asserting that they would unveil evidence of President Trump’s cooperating with the Russians like the “Loch Ness monster, they insist it’s there, even if no one can find it.”

“It’s time for the curtain to close on the Russia hoax. The conspiracy theory is dead,” he said. “At some point I would argue we’re going to have to get back to work.”
