A bipartisan pair of senators is calling for Secretary of State Rex Tillerson to combat Russia's election meddling in Mexico amid reports the Kremlin has become involved in Latin American elections, according to a CBS News report.

Sens. Marco Rubio (R-Fla.) and Bob Menendez (D-N.J.) in a letter ask Tillerson to address the issue when he visits Mexico next week, saying Russia is using "sophisticated technology" to meddle in the country's July presidential election, the network reported.

"We write to urge you to raise the importance of strong, independent electoral systems in Mexico and Latin America more broadly," the two senators wrote to the nation's top diplomat.

"We are increasingly concerned about growing efforts to undermine these hard-fought and widely supported advances, particularly those emanating from outside the region," they added.

White House national security adviser H.R. McMaster last month warned of early signs Russia was meddling in Mexico's election.

"You've seen actually initial signs of it in the Mexican presidential campaign already," McMaster said.

McMaster also noted instances of Kremlin election meddling in Europe.

"As you see, this is really a sophisticated effort to polarize democratic societies and pit communities within those societies against each other and create crises of confidence and to undermine the strength within Europe," he said.

Various congressional panels, as well as special counsel Robert Mueller, are in the process of probing Russia's election meddling in the 2016 U.S. presidential elections. There are also concerns Moscow will interfere in the 2018 midterm elections.

While President Trump has denied allegations of collusion between his campaign and Russia, he did not bring up the issue during his first State of the Union address on Tuesday.
