Well, guess we shouldn't let this bs slide.
I knew your take indicated you had not been following the lead up to Mueller's testimony. I decided to dig up some evidence as to those developments, involving Barr's letter to Mueller:

So, blame the lackey AG Barr for limiting what Mueller could talk about.
Mueller's opening statement refers to the letter AG Barr sent him just days ago, in his second point. Your take is built on your Deep State fiction. Or it's built on a fondness for trolling during peak news cycles...
In a prepared statement at the beginning of his testimony, the special counsel explained why he would not be able to answer many questions to members of the House Judiciary Committee.
“First, public testimony could affect several ongoing matters. In some of these matters, court rules or judicial orders limit the disclosure of information to protect the fairness of the proceedings. And consistent with longstanding Justice Department policy, it would be inappropriate for me to comment in any way that could affect an ongoing matter,” Mueller said, according to his prepared remarks.
“Second, the Justice Department has asserted privileges concerning investigative information and decisions, ongoing matters within the Justice Department, and deliberations within our office. These are Justice Department privileges that I will respect. The Department has released the letter discussing the restrictions on my testimony.”
“I am unable to address questions about the opening of the FBI’s Russia investigation, which occurred months before my appointment, or matters related to the so-called ‘Steele Dossier,’” he said, because the FBI continues to investigate.
“As I stated in May, I also will not comment on the actions of the Attorney General or of Congress. I was appointed as a prosecutor, and I intend to adhere to that role and to the Department’s standards that govern it.”
