(CNN) Republican senators are expected to vote on Wednesday afternoon to acquit President Donald Trump in the third presidential impeachment trial in US history. They would prefer the President not draw attention to that fact on Tuesday night, when he commands the country's attention with his State of the Union address.

Republican Sen. Lindsey Graham of South Carolina said it would be "smart" to focus on other issues, encouraged Trump to be "positive," and posited that "most people" are ready to move on from impeachment.

"I hope he is, too, because I am," said Graham.

In January 1999, President Bill Clinton gave the State of the Union in the same House chamber that had impeached him a month earlier. Clinton would be acquitted by the Senate not long later but did not mention the proceedings in his address. "Clinton handled it pretty well," said Graham, who was a House impeachment manager at the time.
