Former Vice President Joe Biden on Thursday said he hopes Democrats don't try to impeach President Donald Trump if they retake the House of Representatives following next month's midterm elections.

"I hope they don't. I don't think there's a basis for doing that right now," Biden, one of the top Democrats believed to be weighing a 2020 challenge of Trump, said during an interview on "CBS This Morning."


The former vice president said Democrats should wait until special counsel Robert Mueller's Russia probe is concluded before taking any steps against the president. Mueller is currently investigating whether Trump's presidential campaign colluded with the Russian government, and is investigating other related allegations of obstruction of justice against the president.

"There are so many things to attend to immediately," Biden said. "Let's see where the investigation takes us."

Asked whether he thinks a report from the investigation should come out before the midterms, Biden said he thinks it should be issued when the probe is finished. Justice Department regulations prohibit investigators from politically sensitive releases or steps in the weeks leading up to elections, an effort to avoid the impression of partisanship.

“I’ve been around a long time; you wait until the investigation’s finished," Biden said. "You don’t put an arbitrary end to it. You wait until it’s finished, and let’s see what it has to say."

Instead of focusing on the president, Biden urged lawmakers to focus on policy.

"I think we should focus on all the terrible things that are happening now in terms of interest of the middle class people and working class people," he said.

Biden also spoke about one issue he feels he would face if he ran for president: his age.

The 75-year-old said it would be a "legitimate issue." Trump is 72 and would be 74 by the 2020 election. Biden added that he thinks "people are going to judge" him for his age, but that should not discount him.

In a CNN Poll released Sunday, Biden topped the list of candidates that Democratic voters preferred.

“I think they’re going to judge me on my vitality," he said. "Can I still run up the steps of Air Force Two? Am I still in good shape? Do I have all my faculties? Am I energetic? I think it’s totally legitimate people ask those questions.”
