George Conway: 'Trump is like a practical joke that got out of hand' Pelosi endorses Kennedy in Massachusetts Senate primary challenge MORE (D-Mich.), one of two Muslim women serving in Congress, slammed a "white supremacy" agenda in the U.S. after shootings at two New Zealand mosques on Friday left 49 people dead and dozens of others injured.

“From Charleston, to Pittsburgh, Texas, Oak Creek, New Zealand and many places in between, white supremacists are targeting places of worship to push their violent, racist and terrorist agenda,” Tlaib said in part in a statement, referencing other areas where shooters have targeted places of worship.

“This morning I tried to hold back tears as I hugged my two brown, Muslim boys a little tighter and longer. The painful loss of life based on hate makes me so angry. I am so angry at those who follow the ‘white supremacy’ agenda in my own country that sends a signal across the world that massacres like this is some kind of call to action.”

New Zealand authorities announced that four people, including one Australian, had been detained in connection with the attack Friday.
