Key developments this week include a policy change for Pentagon officials and the ongoing government shutdown, as Washington scrambles to respond to the crisis.
The US will eliminate assistance to Colombia and enact tariffs on its exports, after President Donald Trump criticized Colombia's leader Gustavo Petro for not doing enough to stop drug production.
Trump referred to Petro as "an illegal drug leader" who is "low-rated and very unpopular."
Trump announced that Colombia has "no fight against the drugs" and is a "drug manufacturing machine" with "a lunatic" for a president, and that he would impose new tariffs starting in October.
Policy changes for Pentagon officials aim to eliminate miscommunication between Congress and the Pentagon.
Author's summary: Trump imposes tariffs on Colombia and ceases aid.
