Perplexed viewers are questioning Robert Mueller's 'confused' demeanor as he testifies in front of Congress. 

The special counsel faced members of the House Judiciary and Intelligence Committees on Wednesday morning at a highly-anticipated hearing on the Russiainvestigation. 

Viewers reacting on social media have noticed that Mueller appeared to stumble at multiple points. 

'Robert Mueller comes across as a doddering old fool with a questionable moral compass based on situational ethics who should never have been appointed in the first place based on reduced mental capacity,' one person tweeted.  

'Mueller is acting like he doesn't know what's going on,' another wrote. 'He's acting like a confused old man.'  

Some are saying the wobbly performance is a delaying tactic on the part of the special counsel to frustrate Republican committee members determined to discredit findings that are damaging to President Donald Trump.
