3M, the world's largest maker of respirator masks, said Friday it is willing comply with President Trump's order to manufacture and supply more critically needed N95 masks for the United States.

In total, Trump said 3M would produce 166.5 million masks -- nearly all N95s. "Mostly that's going to be for our front line health care workers," he said.

Alleging a fraudulent scheme to drive up costs and damages in dust-mask litigation, 3M Co. obtained court orders, upheld on appeal, to depose a well-known Houston products liability law firm.

3M has sued a medical supply company for allegedly trying to sell its coronavirus-blocking N95 respirator mask for 500% to 600% more than the list price, according to the lawsuit filed Friday.
