Three Minnesota anti-war activists who refused to testify before a federal grand jury in Chicago after their homes were raided in a terrorism investigation have been told they'll be called again, an attorney told The Associated Press on Wednesday.

In late September, authorities searched seven homes and an office in Minneapolis and Chicago in what the FBI said was an investigation into material support of terrorism. Fourteen activists in the two states were summoned to testify, but they refused and their subpoenas were postponed.

None of the activists have been charged. Warrants suggest agents were looking for connections between them and terrorist groups in Colombia and the Middle East.

Bruce Nestor, an attorney who represents some of the activists, said Wednesday that three of them have been told they'll be called back to the grand jury, but it's not clear when. Individual attorneys for those activists are working out details with prosecutors, Nestor said.

"They don't have a specific date, but they are being told that basically they will be called back in front of the grand jury," Nestor said. "They all have individual counsel, and those individual counsel are in the process of discussing with the U.S. attorney the details as to how proceed."

Randall Samborn, a spokesman with the U.S. Attorney's Office in Chicago, declined to comment about the case, saying he could neither confirm nor deny anything involving a federal grand jury because such proceedings are confidential.

Nestor said activists Anh Pham, Sarah Martin and Tracy Molm — whose homes were raided in September — have been told they'll be called again before the grand jury.

"These three are being called back, and within a matter of weeks will be facing the decision of testifying or facing contempt," Nestor said.

Pham said Wednesday she knew little about the situation and declined comment until she had a chance to talk to her attorney. Messages left for Martin were not immediately returned, and a phone number for Molm was not immediately available.

The activists said previously that they wouldn't appear before a grand jury because they felt grand juries had historically been used to harass activists and that testifying in secret would stifle free speech.

The government has not revealed the target of its investigation, but the activists have said they felt singled out because of their work in the anti-war movement.

"The government is not saying much, and they kind of hold all the cards at the moment," Nestor said.
