Almost 3-in-4 Republican voters think the FBI and Justice Department are trying to undermine President Trump, according to a new Reuters/Ipsos poll released on Monday.

Why it matters: This comes in the wake of a four-page memo crafted by Republicans on the House Intelligence Committee. The poll's key finding is especially surprising given Republicans' historical support for law enforcement.

The details on the poll, which was conducted between Feb. 3 and 5:

• 73% of Republican voters said “members of the FBI and Department of Justice are working to delegitimize President Trump through politically motivated investigations," per Reuters.
• About the same percentage of Democratic voters believe Republicans and the White House are trying to interfere with the Russia probe.
• A narrow majority, about 52%, believes Trump or a campaign aide worked with Russia to influence the election.
