For taking a phone call with Taiwan. Liberals were so angry about this. They are the true enemies of peace. It's not because they are Chinese agents. It's because they are dupes for a corporate media that will lie about anything to start a war.
It has nothing to do with Liberals. The U.S. has recognized mainland China as the sole government for decades starting with Nixon normalizing relations with them. Taiwan isn't recognized by the U.S. You and Trump don't know this.
from Wikipedia:
"The United States was allied to the Republic of China during the Pacific War, but broke off relations with China for 25 years when the communist government took over, until Richard Nixon's 1972 visit to China. Since Nixon, every successive U.S. president has toured China. Relations with China have strained under Barack Obama's Asia pivot strategy, U.S. support for Japan in the Senkaku Islands dispute, as well as Donald Trump's threats to classify the country as a "currency manipulator" as part of a potential trade war."
The media has nothing to do with it. You have to turn off the TV and begin reading history books to understand what's going on geopolitically.
