The tangled saga of Democratic presidential frontrunner Hillary Clinton's ongoing email scandal got a little more tangled this week.

The Hill, a newspaper that covers Congress, reports that new emails released by the conservative watchdog group Judicial Watch apparently show Clinton telling a top aide to call her on an unsecure line, when technical troubles made a conversation on a secure line problematic.

"'I give up. Call me on my home #,' Clinton told then-chief of staff Cheryl Mills in a February 2009 email, after more than an hour of trouble trying to communicate via a secure line," The Hill reported, citing the email.

In a separate email, sent at almost the same time, Mills responded, "I just spoke to ops and called you reg line - we have to wait until we see each other b/c [the] technology is not working."

"Pls try again," Clinton responded, The Hill reported.

As The Hill notes, it's unclear whether the conversation actually took place or if the conversation was "moderated" to avoid sensitive topics. But it will add fuel to the fire of critics who say Clinton flaunted secrecy rules while she was the Obama administration's top diplomat.

"This drip, drip of new Clinton emails show Hillary Clinton could not care less about the security of her communications," JudicialWatch's president, Tom Fitton, said in a statement. "How many other smoking gun emails are Hillary Clinton and her co-conspirators in the Obama administration hiding from the American people?"
