Former New York Gov. and Peekskill Mayor George Pataki is making an appeal to fellow Republicans.

He sent out a letter yesterday asking them to stand up against Donald Trump.

The open letter urges Republicans to denounce Trump after his presidential campaign kickoff speech last week in which he declared that some Mexican immigrants bring drugs and crime to the U.S. and are rapists.

Meanwhile, Macy's is the latest company to end its relationship with Trump. Macy's has carried a Donald Trump menswear line since 2004, including $70 button down-shirts and $65 striped ties. Macy's said in a statement that the retailer is disappointed and distressed by Trump's remarks and will end its relationship with him.

Companies have been cutting ties with Trump left and right. NBC, Spanish-language station Univision, TV company Ora TV and Mexican TV network Televisa have all cut ties with Trump, who is suing Univision for $500 million for breach of contract for dropping the Miss USA and Miss Universe pageants.
