Vance congratulates Miller on new Trump administration position

President-elect Trump is expected to pick Stephen Miller as deputy chief of staff for policy in his administration. 

"This is another fantastic pick by the president," Vance wrote, following a CNN report about Trump's pick. 

Miller was a senior adviser in Trump's first term. He helped craft many of Trump's hard-line speeches and plans on immigration. 

Miller has advocated for mass deportations during a second Trump term. He spoke at Trump's massive rally at Madison Square Garden in New York City. 

Miller spoke of the indictments and lawsuits Trump has faced, adding that the former president "took a bullet for democracy" - a reference to the assassination attempt against Trump in Butler, Pa. 

"He was fighting for your children, for your wives, your husbands, everyone that you love and know in the world the right to live in a country where criminal gangs cannot just cross our border and rape and murder with impunity," Miller said of Trump. "Think about how corrupt and hateful and evil a system is that allows gangs to come into this country and rape and murder little girls." 

"Who's going to stand up for our daughters? Who's going to stand up for the girls of America, the women of America, the families of America? Who's going to stand up and say, the cartels are gone, the criminal migrants are gone. The gangs are gone. America is for Americans and Americans only," Miller added.
