Sen. Kamala Harris says she won’t comment again on the investigation into a reported attack on “Empire” actor Jussie Smollett until it’s completed.

Speaking Monday to reporters in Concord, New Hampshire, during her first presidential campaign trip to the state, the U.S. senator from California says that “the facts are still unfolding” and that while she is “very concerned” about Smollett’s initial allegation and it should be taken seriously, “there should be an investigation.”

Harris previously tweeted that the alleged attack was “an attempted modern day lynching.” Police in Chicago say their investigation into the report that the actor was attacked by two men yelling slurs has “shifted” after two brothers were questioned and released. Smollett’s lawyers say the actor feels “victimized” by reports that he played a role in the assault.

The Presidents Day holiday weekend brought Harris and other Democratic presidential candidates to New Hampshire, the state with the first-in-the-nation primary in 2020. Also campaigning in the Granite State were Cory Booker of New Jersey and Amy Klobuchar of Minnesota.

Meanwhile, Sen. Kirsten Gillibrand of New York was back in Iowa, the leadoff caucus state. Former Rep. John Delaney of Maryland, who also is running for president, campaigned in Iowa as well.
