the president's daughter, ivanka, who, it turns out, but using private e-mail for her work in her father's administration. Here's ABC's chief white house correspondent Jonathan Karl. Reporter: Tonight, president trump is defending his daughter, under fire for using her personal e-mail to conduct government business. During the campaign, the president made Hillary Clinton's use of private e-mail a central issue. I think she's pathetic. I think she should be a jail for what she did with her e-mails. Okay? Reporter: Now we are seeing e-mails Ivanka Trump sent white house aides and government officials, including cabinet secretaries from her personal account, using her married name, ivanka Kushner. In one e-mail, obtained by a liberal group through the freedom of information act, she writes "For future reference" and gives her government e-mail. Her lawyer issued a statement saying, "While transitioning into government, Ms. Trump sometimes used her private account, almost always for logistics and scheduling concerning her family." The president today says there's no comparison between Hillary Clinton's actions and his daughter's. Early on and for a little period of time, ivanka did some e-mails. They weren't classified like Hillary Clinton. They weren't deleted. It's all in the presidential records. Everything is there. Jon Karl live at the white house tonight, as well.

All right, our chief white house correspondent Jonathan Karl.
