Trump threatens to send federal agents into New York City amid surge of violence

Donald Trump has again threatened to send federal agents to New York City if local authorities do not stop a surge of violence that has left seven people dead and more than 50 shot since Friday.
The president, who is running for re-election on a law and order agenda as a counterweight to the police and criminal justice reform movement, reacted to the news of the mayhem in his home town on Twitter.
