WASHINGTON, July 10 (Reuters) - A self-identified white supremacist in Pennsylvania was indicted by a federal grand jury after he threatened violence ‌against a member of Congress, Muslims, transgender people and Democrats, the ‌Department of Justice said on Friday.

Here are the details:

• The 12-count indictment by a federal grand ​jury in Pittsburgh named Robert Hlovchiec, 32, as the sole defendant, the DOJ said in a statement, which did not identify the member of Congress.

• Between February and March, Hlovchiec posted comments to YouTube videos where he threatened violence against the member ‌of Congress, Democrats and ⁠liberals, transgender people, and various minority groups like Muslims, the DOJ said.

• "If i get the chance i'm going to do a ⁠mass shooting wherever (member of Congress) is standing. (Member of Congress) needs to die ... America is not for sale. America is not a Muslim country," he said in his threats, ​according to ​the DOJ.

• "If i get the chance I'll ​shoot everyone in (member of Congress)'s ‌family. America is a white Christian nation. We are ready to kill and die before foreigner Muslims take over," the DOJ quoted him as saying.

• The federal grand jury indicted Hlovchiec on "charges of interstate threats and influencing, impeding, or retaliating against a federal official by threat," the DOJ said.

• Hlovchiec identified himself as ‌a Nazi and a white supremacist and expressed ​desires to carry out mass shootings and assassinations, it ​added.

• A representative for the ​defendant could not be reached for comment.

• The FBI conducted ‌the probe leading to the indictment, the ​DOJ said.

• U.S. ​rights advocates have noted rising Islamophobia over the last two-plus decades following the September 11, 2001 attacks, and more recently because of anti-immigration policies, ​white supremacy and the fallout ‌of Israel's war in Gaza.

• U.S. political experts have separately warned ​about political violence from rising polarization.
