The support for a possible House impeachment inquiry against President Biden is growing among the American public, with nearly a quarter of Democrats saying they would back such a move, a new poll has found.

According to the NPR/PBS NewsHour/Marist poll released Wednesday, 49% of U.S. adults say they would support the House of Representatives officially launching an impeachment inquiry into Biden amid allegations of corruption within his family, compared to 48% who would not.

That number is up from the same survey in October that found 47% supported such a move, and 52% would be opposed.

An impeachment inquiry is most notably supported by 24% of adults identifying as Democrats, although a majority (74%) would still be opposed.

The poll found that Biden's approval rating remains heavily underwater, with just 40% of adults approving of his job performance as president and 53% saying they did not approve.

That number is weighed down heavily by those identifying as independents, with just 36% approving of his job performance and 59% disapproving.
