US senators have called on the Federal Trade Commission (FTC) to step up its investigation into Google over alleged anti-trust practices after the European Commission called on the firm to address a number of concerns it has raised on these issues.
The senators, Herb Kohl and Mike Lee, both of whom were involved in a feisty session with Google's chief executive Eric Schmidt in September 2011, said the deal offered by the EC was a positive step forward in addressing the concerns they also have with the firm.
"We are pleased that the EU is working with Google to develop a set of voluntary solutions to the search engine's problematic practices, including those that we identified at our September 2011 hearing," they said.
"We are hopeful that Google will be a willing partner with the EU's Competition Commissioner."
The senators also called on the FTC to step up its investigation by considering both the issues they have previously raised and those singled out by the EC. At issue is whether Google is abusing its dominant search position.
"We continue to urge the FTC to investigate the concerns we raised at our hearing and to ensure a competitive search market where consumers can fairly pick the winners and losers in our online economy," they added.
Google has long denied that it has ever altered search results in its system to favour its own products. Schmidt told Lee at the hearing last September that Google never "cooked" any search results.
