Doug Mastriano, the Republican nominee for governor in Pennsylvania, plans to appear Tuesday for a deposition by the select House committee investigating the January Capitol riot, his lawyer told CNBC.

The politician expects to leave in less than 10 minutes because of an unresolved issue over the terms of his deposition.

The panel needs to agree not to edit video clips of his appearance and release a potentially misleading video after he testifies.

The lawyer said that Mastriano was concerned that the video could affect his chances in the governor's race.

He has nothing to hide, according to Parlatore.

A spokesman for the committee refused to speak to CNBC.

The panel wants to know if Mastriano helped Trump reverse his loss in the 2020 campaign to Biden.

In February, the committee's chairman wrote a letter to Mastriano, saying that he had knowledge of and participated in a plan to arrange for an alternate slate of electors to be presented to the president.

Parlatore said that he had issues with the deposition because he was a political candidate.

According to Parlatore, no one can be forced to testify in a private session over a technicality. The committee does not have a ranking member, according to him.

Mastriano is willing to testify in public, but only if his conditions are met. The lawyer said he wouldn't be able to force the panel to comply with the conditions before they testified.

McCarthy pulled his picks from the committee after Pelosi rejected two of them. The ranking member of the committee is not the vice chair.

If his expectations for the deposition come to pass on Tuesday, Parlatore will start drafting a lawsuit.

According to multiple federal judges, Cheney is the ranking member of the select committee, despite being appointed to the rank of vice chair by the Democrats.
