WASHINGTON, May 1 (Reuters) - The chair of the House

Oversight Committee said Wednesday he is investigating the

Federal Trade Commission's (FTC) work with the European

Commission in the collapse of Amazon.com's ( AMZN ) plan to

acquire iRobot Corp ( IRBT ) in a $1.4 billion deal.

Amazon ( AMZN ) and robot vacuum maker iRobot in January dropped

their plans to tie-up in the face of opposition from European

and U.S. antitrust regulators.

"The FTC's anticompetitive actions threaten to harm

America's global position in the personal robotics market, while

ceding market share of personal robotics to foreign entities

such as China," Republican Representative James Comer said in a

letter to the FTC asking for documents shared by the FTC with

the European Commission
