U.S. stock futures are following world markets lower after closely-watched speeches by Federal Reserve Chairman Ben Bernanke and President Barack Obama.

Bernanke said that weak consumer spending is hurting the economy. He offered no new details about plans to spur growth. Stocks slid after Bernanke spoke Thursday afternoon.

Thursday evening, President Obama unveiled a $447 billion package of tax cuts and new spending to stimulate job growth. Its chances of passing Congress are uncertain. Republicans control the House and many of them oppose any new spending.
