Thousands gathered in dozens of cities around countries to mourn the unarmed black teenager shot to death early last year, and to add their voices to a debate on race that his death has set off.

Buoyed by re-election, he said the nation must pursue without delay steps to protect children from gun violence, tackle climate change and overhaul fractured immigration laws.

Today, however, there seems little appetite from either Democrats or Republicans in Washington for a federal rescue of the birthplace of the automobile industry.
