Fox News reporter Jana Winter is expected to be a Colorado courtroom Today.
The suspect's lawyers in the Colorado theater shootings want to know how Winter got some information after a gag order was issued.
The court is expected to hear arguments on whether she must testify about her confidential sources for a story on the suspect.
Winter quoted unnamed law-enforcement officials as saying theater shooting suspect James Holmes had sent a psychiatrist drawings that may have shown signs before the July shootings in which 12 people were killed.
Holmes' lawyers say whoever gave Winter that information violated a gag order. They want to know Winter's sources.
Winter's lawyers say that Colorado's shield law protects her from having to disclose her sources. Holmes' attorneys say they'll be ready to argue that point.
Also, prosecutors are expected to announce Today whether they will seek the death penalty against Holmes.
