BREAKING: Ex-Trump aide Nunberg reverses: Mueller probe is NOT a 'witch hunt'

Former Trump campaign aide Sam Nunberg says that he believes special counsel Robert Mueller's investigation into Russia's meddling in the 2016 election is "warranted," walking back his previous remarks calling the probe a "witch hunt."

"No, I don't think it's a witch hunt. There's a lot there, and that's the sad truth," Nunberg told ABC News in an interview broadcast Saturday, a day after he answered a subpoena by Mueller's team to testify before a federal grand jury on his time in the campaign.

The former aide, who appeared for hours before a grand jury on Friday, said he was grilled about current and former Trump staffers being scrutinized as part of the special counsel's probe into ties between Trump campaign associates and Russia.

After his testimony, Nunberg said he's "very worried" about Roger Stone, a longtime Republican strategist who informally advised Trump during the early stages of the campaign. “He's certainly at least the subject of this investigation, in the very least he's a subject.”
