The proposal is a signal that some in Congress intend to push back on the Trump administration's moves to explore an improvement in relations with Moscow, Bloomberg said.
Panel Chairman Mike Crapo of Idaho and top Democrat Sherrod Brown of Ohio said their bill would authorize "broad" new sanctions targeting sectors of Russia's economy including mining, metals and railways.
It would codify and strengthen existing sanctions included in executive orders affecting Russian energy projects and debt financing in key economic sectors, the senators said in a press release.

"There is significant congressional interest in ensuring sanctions on Russia are effective and proportionally enhanced, particularly in light of continuing Russian intransigence in these areas."
The question of Russian sanctions has been raised by a number of senators in both parties after the intelligence community announced in January its conclusion that Russia interfered in the 2016 election on behalf of President Donald Trump.
Among those seeking more sanctions is Republican Senator Lindsey Graham of South Carolina, who has said he would try to attach such a measure to bipartisan Iran sanctions legislation expected to be sent to the Senate floor.
