HBO host Bill Maher tore into special counsel Robert Mueller on Friday night, saying the report released by "Prosecutor Jesus" did not leave an adequate road map for President Trump's impeachment.

"The attorney general is corrupt. The Congress is dysfunctional. What good is leaving a road map for impeachment if you know a tribal, party-before-country Republican Senate will never remove the president?" Maher said. "Bob, your trail of bread crumbs isn't good enough. We're not that smart anymore."

"America is an aging shortstop. You have to hit it right at us," he added.

Maher chastised Democrats for having "done f--- all about" Trump's antics since he came into office because they were waiting for Mueller's report.

"We all sat around waiting for Prosecutor Jesus to turn in his big report, and he came back with 'ask someone else.'" Maher said. "We needed Superman and we got Clark Can't."

"I get it. Mueller's a Boy Scout, a straight arrow. He played it by the book," Maher continued. "But you may have noticed for the past three years, we've kind of been off-book. And greatness sometimes means not doing everything by the book."

"All [Mueller] had to do is what people in the justice system do every day - use the law to come to justice, not be so restricted by technicalities that the bad guys win," Maher said.

The HBO host knocked the special counsel for not forcing Trump or his eldest son, Donald Trump Jr., to testify under oath. He also berated Mueller's office for failing to obtain Trump's tax returns so they could "follow the money."

"Rudy Giuliani said this week there's nothing wrong with taking information from Russians," Maher said. "That's where we are now. I lay that on Mueller."

Maher said Mueller created new precedents by refusing to recommend any charges against the president, arguing that officials will now have the green light to meet with foreign governments, invite them to hack opponents and break campaign finance laws.

"That's what law is - new precedents. It's always evolving. You can't indict a sitting president? It's not in the Constitution. It's not even a law. It's a guideline like drinking white wine with fish or not f---ing your cousin," Maher said.

Mueller's long-awaited 400-plus-page report, which was released in a redacted form last week, detailed extensive Russian efforts to help Trump win the 2016 election but found that no one from the Trump campaign conspired with Moscow to interfere in the 2016 presidential race against Hillary Clinton.

The special counsel also outlined 10 instances of Trump potentially obstructing justice over the course of Mueller's investigation, including the firing of James Comey as FBI director.

Mueller declined to offer a traditional prosecutorial judgement, leaving the decision up to Attorney General William Barr and Deputy Attorney General Rod Rosenstein, who then determined there was not sufficient evidence to charge the president.
