The United States’ largest fuel pipeline has been shut down since Friday after a cyber attack, and it’s not clear how long the outage will last. CNBC’s Brian Sullivan reports that the outage could lead to spot shortages of gas, diesel, and jet fuel, and CNBC’s Eamon Javers details the “DarkSide” hacking group reportedly responsible for the attack. The disappointing April jobs report sparked debate about why American hiring hasn’t picked up as quickly as economists expected. CNBC’s Steve Liesman and Rahel Solomon discuss whether the U.S. economy might experience a lasting shortage of labor after the jobs miss. Anthony Scaramucci, founder of Skybridge Capital, says unemployment benefits are not to blame; most Americans want to work. Scaramucci also recaps Elon Musk’s appearance on “Saturday Night Live” and the resulting dogecoin nosedive. The Biden administration announced last week that it supports waiving intellectual property protections for Covid-19 vaccines in order to address the global shortage. Dr. Scott Gottlieb, member of the boards of Pfizer and biotech company Illumina and former FDA Commissioner, says the patent won’t solve the immediate problem of global vaccine distribution. Gottlieb also discussed his thoughts on the quickly-changing federal guidance on coronavirus restrictions.
