Administration officials had promised to release roughly 2,000 pages of Clinton’s emails on Friday, but said they would not meet a court deadline for releasing the final 7,000 pages.

That means the final batch of emails won’t be released until after voters go to the polls in the first several primary states, where Clinton is facing off against Sen. Bernie Sanders (I-Vt.).

State insisted late Thursday that it “regrets” not publishing the entire cache as ordered by a federal court last year. It defended the holdup as the result of an internal oversight exacerbated by last weekend’s massive blizzard.

The Obama administration revealed Friday it is withholding 22 emails from the trove because they are classified “top-secret.”

Scrutiny over Clinton’s use of a private email server has cast doubt on her trustworthiness for the presidency. Critics say her technology habits prevent accountability and transparency of her actions at State.

Clinton’s campaign has repeatedly called for the public release of all her agency emails in an attempt to quell the email drama.

She leads Sanders by about 3 points in Iowa, according to the latest RealClearPolitics average.
