The U.S. Department of Justice's trial on proposed penalties against Alphabet's Google over its dominance in the online search market will not be delayed to accommodate any changes Trump administration officials wish to make, the judge overseeing the case said on Tuesday.

U.S. District Judge Amit Mehta said he would not move the trial, scheduled for April, for that purpose.

"If there is going to be a re-evaluation of the remedies that are being requested, it needs to be done quickly," the judge said.

Prosecutors have asked the judge to order Google to sell its Chrome browser, share data and search results with rivals and take other measures - including possibly selling the Android mobile operating system.

Google has called the proposals staggering, and said they would harm American competitiveness.
