Rumblings of breaking up Big Oil

Lawmakers at a Joint Economic Committee hearing Wednesday talked about breaking up the oil companies.

Pointing to the example set by trustbuster Teddy Roosevelt a century ago, a group of lawmakers led by Sen. Charles Schumer, D-N.Y., are questioning whether they should step in to roll back the mergers that have created the so-called “supermajors” like Exxon Mobil Corp., Chevron Corp. and ConocoPhillips, a notion that sends shivers through the oil sector.
