Washington: American domestic politics has experienced a new low with President Donald Trump and House Speaker Nancy Pelosi engaging in an unprecedented war of words on the issue of pull out of US forces from Syria, a move that paved the way for Turkey to launch cross-border military operations against US-ally Kurdish forces.

The war of words on Wednesday between the two leaders started after the White House had invited the leadership and top committee members of both Democrats and Republicans, and the Congress to brief them about their policy on Syria.
