There are still a lot of unanswered questions."The ICE building where Wednesday's shooting happened had recently received a bomb threat, Department of Homeland Security (DHS) spokesperson Tricia McLaughlin said on Fox News.Texas Gov. Greg Abbott responded to the shooting on X, stating that Texas "fully supports ICE.""This assassination will NOT slow our arrest, detention, & deportation of illegal immigrants," Abbott added without further context."We will work with ICE & the Dallas Police Dept. to get to the bottom of the assassin’s motive.US Vice President JD Vance posted a statement on social media Wednesday morning saying, “The obsessive attack on law enforcement, particularly ICE, must stop. I’m praying for everyone hurt in this attack and for their families.”"This must stop," Texas Republican Sen. Ted Cruz said during Wednesday's news briefing. "This is the third shooting in Texas directed at ICE or [Customs and Border Protection]."
