Who is Attorney General William Barr?

President Donald Trump has asserted executive privilege over materials special counsel Robert Mueller used to assemble his report on Russian interference in the 2016 election. Attorney General William Barr, who faces growing backlash from House Democrats after refusing a subpoena that called for the release of those very materials, has long been an advocate of broad executive power.

It's Friday, and Signal readers deserve at least one entirely upbeat news story.

José Obdulio Gaviria, a Colombian senator for the rightwing Democratic Center party, is an outspoken opponent of government attempts to make peace with the FARC rebel group after 50 years of conflict.

On his way into a meeting earlier this week, Gaviria collapsed. It was later reported that he had fainted as a result of low blood pressure probably caused by complications following recent open heart surgery.

A political rival, Senator Julian Gallo, quickly came to his rescue and revived him using resuscitation skills he learned as—irony alert—a FARC guerrilla. CPR applied by Gallo helped Gaviria regain consciousness, before another senator, who is also professional doctor, took over. Gaviria was taken to hospital and appears to have recovered.

Because some things will always be more important than politics.
