By Patricia Zengerle, Richard Cowan and Timothy GardnerWASHINGTON, July 28 (Reuters) - The U.S. Senate advanced sweeping Russian energy sanctions legislation on Tuesday as Ukrainian President Volodymyr Zelenskiy visited the Capitol, seeing the vote as a tribute to the bill's author, the late Senator Lindsey Graham, on the day of his funeral.Graham was among Kyiv's most influential and outspoken allies in Congress in its four-year-old war against Russia, and the bill aims to increase economic pressure on Moscow over its invasion of Ukraine.

Kyiv is moving beyond aid requests toward co-production and sanctions as Congress weighs how much pressure to put on Moscow.

One of the aides said the Senate was also expected to begin voting during Zelensky's visit on a bill to impose sanctions on Russia that was championed by Graham.
