CNN's Jake Tapper ridicules Rudy Giuliani for telling Mueller to 'put up or shut up' after not saying a word for over a year

In wake of President Donald Trump's lawyer saying that special counsel Robert Mueller should "put up, or shut up," CNN's Jake Tapper couldn't help but laugh.

"Put up or shut up?" Tapper questioned at the top of his Wednesday episode of "The Lead."

"Shut up?" he continued. "I haven't heard him say a word in a -- in a year."

The host noted that the move comes after President Donald Trump escalated his attacks on the Mueller probe in what has become an almost daily Twitter meltdown. He also described the investigation as having gone further into the depths of a president's team since Richard Nixon.

Trump lawyer Rudy Giuliani claimed the president was not obstructing justice by saying that Attorney General Jeff Sessions should shut down the investigation. He said that Trump was just expressing his opinion, not giving an order.

"The President is the President of the United States, so they're considered official statements by the President of the United States," said former press secretary Sean Spicer, when asked how the press should characterize Trump's tweets.

In a panel discussion, former White House communications director Jen Psaki said that anything that came from President Barack Obama's mouth was an official statement.
