CIA Director Mike Pompeo did not disclose last year that he owned a business linked to a Chinese government-owned company, McClatchy reported.

Pompeo - who was recently nominated by Trump to be secretary of State - failed to disclose his business' ties to a Chinese government oil and gas company in the questionnaire he was required to fill out to be confirmed as CIA director by the Senate.

That omission could be an issue for him during his confirmation hearing before the Senate Foreign Relations Committee on Thursday to be secretary of State.

Senators did not bring up his links to the Chinese government during his confirmation to be CIA director last year. He was confirmed by a 66-32 vote, with 14 Democrats voting in favor of his confirmation.

Pompeo will need at least a few Democrats to support his confirmation. Sen. Rand Paul (R-Ky.) has opposed his nomination, and Sen. John McCain (R-Ariz.) will not be present for the vote as he continues receiving cancer treatment.

Democrats who supported his CIA nomination last year - especially those who are vulnerable in the upcoming midterm election - are rethinking whether they will support Pompeo this time around and could hinder his confirmation.
