U.S. Justice Dept will sue to stop Halliburton, Baker Hughes merger: source

The antitrust lawsuit could potentially scupper the deal that was first announced in November 2014 to combine the No. 2 and No. 3 oil services companies. Since then, oil prices have fallen by more than 55 percent. Faced with opposition from the Justice Department, the companies may either cancel the planned tie-up or fight the government in court.
