The plea from Rep. Jim Himes (D-Conn.) comes a week before the Dec. 19 vote, which is expected to affirm the results of the Nov. 8 election, in which Trump beat Clinton with 306 Electoral College votes.

“We’re 5 wks from Inauguration & the President Elect is completely unhinged. The electoral college must do what it was designed for,” Himes wrote Sunday night on Twitter in response to Trump’s gripe that NBC “Nightly News” is “biased, inaccurate and bad, point after point.”

In an interview Monday on CNN’s “New Day,” Himes said that Trump’s refusal to say that the Russians hacked Democrats during the election was what prompted his plea to the Electoral College.

“What finally pushed me over the edge was when the president-elect of the United States criticized the CIA and the intelligence community. Can you imagine what the leaders in Beijing and Moscow and Tehran are thinking as they watch the next president of the United States delegitimize and criticize his own intelligence community and stand up for the defense of Russia, one of our prime adversaries,” said Himes.
