U.S. Senator Marco Rubio has introduced legislation to name the street in front of the Russian Embassy in Washington Boris Nemtsov Place in honor of the slain opposition politician.
Rubio (Republican-Florida) proposed the bill on February 27, two years after Nemtsov was shot dead on a bridge near the Kremlin.
Rubio, who unsuccessfully sought the Republican presidential nomination in 2016, said that Nemtsov "was just one of [Russian President] Vladimir Putin’s critics who have wound up dead or hospitalized as the regime cracks down on any opposition."
"The creation of 'Boris Nemtsov Plaza' would permanently remind Putin’s regime and the Russian people that these dissidents' voices live on, and that defenders of liberty will not be silenced," Rubio said in a statement.
"Whether it is looking at a street sign or thousands of pieces of correspondence addressed '1 Boris Nemtsov Plaza,' it will be abundantly clear to the Kremlin that the intimidation and murder of opposition figures does not go unnoticed."
Some 15,000 Russians marched through Moscow on February 27 to honor Nemtsov and call for justice, and thousands rallied in other cities.
Five suspects are being tried for Nemtsov's killing, but his relatives believe those who carried out the contract-style killing were following orders from someone higher up.
For Rubio's resolution to become U.S. law, it must be passed by both houses of Congress and signed by President Donald Trump.
