New York, October 4: Three New York residents have filed a lawsuit against US President Donald Trump and administrator of the Federal Emergency Management Agency (FEMA) William Long, over the new Presidential Alert messaging system.

The plaintiffs express concern over the possibility of Trump broadcasting arbitrary, biased, irrational messages and there is no way to opt out of the system, Cnet reported. Donald Trump Demands Urgent Changes in Global Trade, Defends Tariff War with China.
