The report is nearly 400 pages and covers subjects ranging from questions about Russian interference in the 2016 US presidential election to whether President Donald Trump obstructed justice.

(CNN) — Robert Mueller’s investigation into possible obstruction of justice could not clear President Donald Trump, saying that it was unable to determine “that no criminal conduct occurred,” according to a redacted version of the special counsel’s report released Thursday.

Mueller’s investigation into possible collusion found that members of the Trump campaign knew they would benefit from Russia’s illegal actions to influence the election, but didn’t take criminal steps to help, it report said.

Mueller also makes clear Congress can continue to investigate Trump.

“With respect to whether the President can be found to have obstructed justice by exercising his powers under Article II of the Constitution, we concluded that Congress has the authority to prohibit a President’s corrupt use of his authority in order to protect the integrity of the administration of justice,” the report said.

In the report, Mueller provided a legal justification for why the special counsel was able to investigate obstruction of justice, even if it could not indict a sitting president. The lengthy section, citing legal precedents, also alludes to Congress’ power under checks-and-balances to investigate and potentially impeach the President over obstruction of justice.

“The conclusion that Congress may apply the obstruction laws to the President’s corrupt exercise of the powers of office accords with our constitutional system of checks and balances and the principle that no person is above the law,” the report states.

The investigation has clouded Trump’s presidency for nearly two years, and Trump was clearly worried about the potential findings of Mueller, the former FBI director.

In May 2017, after Trump learned of Mueller’s appointment, Trump “slumped back in his chair and said, ‘Oh my God. This is terrible. This is the end of my Presidency. I’m f***ed.'”
