Former special counsel Robert Mueller will testify today at congressional hearings.
The hearing will be televised.
The testimony is high stakes for both Democrats and Republicans.
The Democrats are hoping that the hearing will weaken support for Trump leading up to the 2020 election.
Wednesday's first hearing gets underway at 10:00 am.
Mueller has stated that he will not go beyond what's already been revealed in his report.
President Trump has already offered commentary on the proceedings.
