"Fox News Sunday" host Chris Wallace grilled Trump campaign adviser Mercedes Schlapp on why the president's Saturday rally in Tulsa saw lower-than-expected attendance, despite claims by Trump last week that 1 million people had requested tickets.

The big picture: As Wallace pointed out, the president frequently touts crowd sizes at his rallies as an indicator of enthusiasm and support. The Trump campaign planned for a massive crowd by setting up an outdoor overflow section for supporters who were shut out of the city's BOK Center, which has a total capacity of 19,200.

  • The attendance ended up clocking at just under 6,200, according to the Tulsa Fire Department, and the campaign canceled the outdoor portion of the event.
  • Schlapp blamed the underwhelming turnout on "protesters," claiming that supporters who wanted to attend were "worried about the protesters who were coming in." Tulsa World reported that police only arrested one protester for trespassing in a secure area.

The exchange:

SCHLAPP: "I'd love to see a Joe Biden rally. Let's bring it on, because there is no comparison. The phenomenon of the rally came because of President Trump, and people came out. Those people that knew that they wanted to be there physically present with the president. They joined us, and they're family oriented individuals who wanted to come out and be with us." *CROSSTALK*
WALLACE: "Mercedes, please don't filibuster. We're showing pictures here and it shows big, empty areas. Frankly, it makes you guys look silly when you deny the reality of what happened."

What they're saying: Schlapp continued to deflect from the crowd size and attack Biden, calling him a "failed politician" and stating that Trump used the rally to "talk about the failed record of Joe Biden."

  • "Joe Biden has been a career politician that has done nothing but supported failed institutions."
  • "There were empty seats there," Wallace said. "You're shifting to a campaign speech which has nothing to do with the attendance of the rally."

President Trump and Joe Biden are going back and forth over the former vice president's "buy American" economic proposal, which Trump claims Biden "plagiarized" from him.

Robert Mueller speaks out on Roger Stone commutation

Former special counsel Robert Mueller responded to claims from President Trump and his allies that Roger Stone was a "victim" in the Justice Department's investigation into Russian interference in the 2016 election, writing in a Washington Post op-ed published Saturday: "He remains a convicted felon, and rightly so."

Why it matters: The rare public comments by Mueller come on the heels of President Trump's move to commute the sentence of his longtime associate, who was sentenced in February to 40 months in prison for crimes stemming from the Russia investigation. The controversial decision brought an abrupt end to the possibility of Stone spending time behind bars.
