Charles Krauthammer’s son Daniel on Thursday said he is still grappling with grief after the lost of the conservative author, Pulitzer Prize-winning columnist, and Fox News commentator earlier this year.

“I’m OK. It’s still a hard time, it’s still very recent and fresh. But I’ve really dedicated myself in this time since to completing his book for him. That’s something he entrusted to me, and it’s something I’ve taken more seriously and more meaningfully than probably anything else I’ve ever done,” Daniel Krauthammer told “The View” co-host Whoopi Goldberg. “That’s been hard, but it’s also been good, and I felt like I’ve been able to fight for him still, and to do what’s right by him, and also by everyone else who read him and looked at him.”
