The Justice Department is expected to announce later Friday that Rep. Henry Cuellar (D-Texas) has been indicted on unknown charges.

Cuellar, a pro-life moderate who has been critical of President Biden’s handling of the border crisis, issued a statement shortly after NBC News reported that an indictment would be made public.

In the statement, Cuellar said he and his wife, Imelda, were “innocent of these allegations” and added that he had acted “consistent with the actions of many of my colleagues and in the interest of the American people.”

A source told NBC News that Cuellar’s congressional staff had reached out to other aides on Friday morning for advice on responding to the imminent charges.
