Pelosi, Schumer: Barr's Mueller summary 'raises as many questions as it answers'

"Attorney General [William] Barr’s letter raises as many questions as it answers," Pelosi and Schumer said in a joint statement. "The fact that Special Counsel Mueller’s report does not exonerate the president on a charge as serious as obstruction of justice demonstrates how urgent it is that the full report and underlying documentation be made public without any further delay."

Barr on Sunday delivered a letter to Congress summarizing the key findings of Mueller's investigation into the Trump campaign's ties with Russia.

According to Barr's letter, Mueller found no conclusive evidence that Trump or his team conspired with the Russian government to interfere with the 2016 election. The letter also says Mueller made no conclusion on whether Trump obstructed justice.

The findings were seen as vindication by Trump's allies, who argued that the report closed the chapter on the ongoing Trump-Russia saga for good. The president himself claimed Barr's letter was a "complete and total exoneration."

But Democrats were also quick to seize on some of the findings outlined in the letter. Though the letter said Mueller had not reached a conclusion regarding obstruction of justice, Barr and Deputy Attorney General Rod RosensteinRod RosensteinTrump: Appointing Sessions was my biggest mistake Trump blasts Mueller, decries 'witch hunt' at 2020 launch Trump: I didn't fire Mueller since firings 'didn't work out too well' for Nixon MORE had decided there was not enough evidence to press obstruction of justice charges against Trump.

That decision led to immediate calls for the report to be made public.

"The American public deserves the full report and findings from the Mueller investigation immediately — not just the in-house summary from a Trump Administration official," Booker tweeted.

Their statements provide a hint of the political battle to come as calls mount for more information regarding the report from the Department of Justice. Trump's lawyer Rudy Giuliani said on Sunday that he supports the report being released publicly as well.

"We would all like it to happen because if it doesn’t happen, somebody is going to say there is something in there," Giuliani said on CNN.
