Alex Jones arrives at the Travis County Courthouse in Austin on Tuesday.

 Conspiracy theorist Alex Jones testified Wednesday that he now understands it was irresponsible of him to declare the Sandy Hook Elementary School massacre a hoax and that he now believes it was "100% real."

Speaking a day after the parents of a 6-year-old boy who was killed in the 2012 attack testified.

Jones said at his trial to determine how much he and his media company, Free Speech Systems, owe for defaming Neil Heslin and Scarlett Lewis.

About the suffering, death threats and harassment they've endured because of what Jones has trumpeted on his media platforms, the Infowars host told a Texas courtroom that he definitely thinks the attack happened.

Jones told the jury that any compensation above $2 million "will sink us," but added: "Ï think it's appropriate for whatever you decide what you want to do."

Testimony concluded around midday and closing arguments are expected to begin Wednesday afternoon.

Jones said he does, but added, "They (the media) won't let me take it back."

Jones has already tried to protect Free Speech Systems financially.
