Jerry Nadler, the House Judiciary Chairman, said Sunday that former Special Counsel Robert Mueller's hearing will focus on finding any wrongdoing that could warrant impeachment.

The Democrat from New York said the committee expects to find 'very substantial evidence' that Trump is guilty of 'high crimes and misdemeanors,' which would meet the standards for impeaching the president.

When asked by Fox News host Chris Wallace why the Democrats on the committee want to put the American people and Mueller through another Russian collusion related hearing, Nadler said they want Mueller to share the facts directly with Americans.

House Judiciary Chairman Jerry Nadler told Fox News Sunday morning that the hearing with Robert Mueller this week intends to focus on finding evidence to impeach Donald Trump

He said the committee expects to find 'very substantial evidence' that Trump is guilty of 'high crimes and misdemeanors,' which would meet the standard for impeachment

Special Counsel Robert Mueller was supposed to testify before the committee last week, but the hearing was delayed until Wednesday to give him more time to prepare

'We want the American people to hear directly from Special Counsel Mueller what his investigation found,' Nadler said Sunday morning. 'The president and the attorney general and others have spent the last few months systematically lying to the American people about what the investigation found.'

Both Attorney General Bill Barr and President Donald Trump have said the investigation found no evidence that there was collusion between Trump and the Russian government to influence the 2016 elections.

They also claim there was no obstruction – an assertion Democrats deny is true.

Since the report was released, Democrats have clung to the 10 instances outline by Mueller of potential obstruction of justice throughout the probe.

Many said this is enough to warrant launching impeachment against Trump.

Nadler also said they called the hearing because Democrats want the American public to hear directly from Mueller – suggesting they would hear different facts than what Trump and his attorney general have been spewing

Trump and Attorney General Bill Barr claim the report fully exonerates the president, adding the report found no evidence of collusion with the Russian government or obstruction of the probe

Nadler and other Democrats, however, claim there is enough evidence for obstruction in the report that should lead to impeachment proceedings against Trump

Mueller will appear before the House Judiciary Committee on Wednesday – after his hearing was delayed last week – and will answer questions related to the findings of his investigation.

The hearing comes several weeks after Mueller issued a statement from the Department of Justice pleading that lawmakers allow the more than 400-page report stand for itself, claiming he would not speak further on the matter.

He also announced he was stepping down from the DOJ.

Nadler told Fox that the purpose of Wednesday's hearing is to have findings presented to the American people and then 'go from there' because 'no president is above the law.'

That report declined to make a prosecutorial judgment on whether to charge Trump, partly because of a Justice Department opinion that sitting presidents shouldn't be indicted.
