(Reuters) - More Republican lawmakers complained on Thursday about U.S. President Donald Trump’s inflammatory attacks on four Democratic lawmakers, all minority women, after chants of “send her back” by Trump supporters at a rally targeted one of them.

More than 40 of the 250 Republicans serving in the U.S. Congress as of Thursday morning had criticized Trump over his attacks, widely condemned as racist, on the four: Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts and Rashida Tlaib of Michigan.

After tweeting over the weekend that the four should “go back” where they came from, even though all of them are U.S. citizens and three were born in the United States, Trump stepped up his vilification of them at a rally on Wednesday.

As Trump recounted past comments by Omar, who was born in Somalia and emigrated to the United States as a child, the crowd began chanting: “Send her back!”

Here is a list of Republicans in Congress who have voiced some level of concern about Trump’s contentious remarks.
