He added that there are more pressing issues to address, such as what he views as attacks on unions and neglect of the Environmental Protection Agency.

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

Democrats need to pick up 23 seats in the House in next month's midterms to reclaim the majority.

Some liberals have pushed for the party to make impeachment a priority if in fact Democrats secure a majority, but party leaders have repeatedly said the issue is not at the top of their agenda.

Instead, top Democrats have said they intend to focus on campaign finance reform, and would launch investigations into issues involving the president if they took over the House.

Some party members previously moved to introduce articles of impeachment against the president, but the measure failed overwhelmingly.
