Trump Targets Elite Colleges' Visa Programs as Iran Tanker Attacks Rattle Oil Markets

The Trump administration is launching investigations into the use of foreign exchange visa programs at nine top colleges, including Harvard, Stanford, and MIT, in its latest broadside against international students and scholars at elite schools. Bloomberg's Mike Shepard joins from Washington to explain what the probes mean for universities and the foreign workers and students they host. Meanwhile, oil prices surged after fresh tanker attacks by Iran threatened to curtail a recent uptick in flows from the Middle East. The strikes add new risk to energy markets already sensitive to any disruption in the region. The developments unfold against the backdrop of President Trump's statement that the US would not attack Iran ahead of November's midterm elections, a pledge that leaves markets weighing whether de-escalation will hold or whether Tehran will test Washington's restraint.
