Senior US Democratic officials said President Donald Trump’s administration should immediately impose sanctions on Russia after US intelligence told Congress members that Russia seems to be trying to influence the US presidential election this year, Reuters reported.

Senators Chuck Schumer, Bob Menendez, and Sherrod Brown wrote to Secretary of State Mike Pompeo and Secretary of the Treasury Steven Mnuchin, demanding the US presidential administration immediately and decisively impose sanctions on the Russian government and Russians involved in the election.

A source in Congress earlier reported intelligence officials told lawmakers that Russia seems to be conducting disinformation and propaganda campaigns to help both Democratic presidential candidate Bernie Sanders and Trump, who will be seeking re-election in November.

The Kremlin rejected any allegations on interference.

The US law allows the administration to propose sanctions on Moscow responding to the interference with the election. Congress passed the Countering America’s Adversaries Through Sanctions Act in 2017 partly in response to the intelligence community’s finding that Russia interfered in the 2016 election to boost Trump’s chances of winning the White House. Moscow denies allegation, while Trump has repeatedly questioned the finding.

The White House, the State Department and the US Treasury did not respond to a request for comment.
