Sen. Lindsey Graham, R-S.C., one of President Donald Trump's strongest supporters on Capitol Hill, said Saturday he will use his power to squash the impeachment effort as soon as possible.

Speaking to CNN's Becky Anderson in front of a crowd in Doha, Qatar, Graham was asked about the Democrats' effort to impeach Trump over allegations that he used his office for political gain earlier this year.

"I don't know where this goes, but I know impeachment will be over soon. I supported the Mueller investigation, by the way, for those who care about domestic politics. I didn't know what Trump had done with the Russians. What have I come to believe? There is no collusion between the Trump campaign and the Russians," Graham said before pivoting to the impeachment topic.

"Mueller spent two years and $25 million looking at all things Trump and Russia, and now we're impeaching the president of the United States by partisan people, no outside counsel involved. This thing will come to the Senate and it will die quickly, and I will do everything I can to make it die quickly."

Graham, who chairs the Senate Judiciary Committee, added, "I want this to end as quick as possible for the good of the Senate, for the good of the country, and I think the best thing for America to do is get this behind us. … If you don't like President Trump, you can vote against him in less than a year. It's not like a politician is unaccountable if you don't impeach him. So I think impeachment is going to end quickly in the Senate. I would prefer it to end as quickly as possible."

The House Judiciary Committee voted Friday to advance two articles of impeachment against Trump. The full House chamber could vote on them next week before lawmakers break for Christmas.

If the House impeaches Trump on one or both articles, the Senate would then hold a trial on whether to remove him from office.

Graham said any Senate trial would be swift and would not include witnesses.
