Fentanyl threatens Dems' push against Trump on tariffs

• It would overturn Trump's emergency declaration allowing him to place tariffs on Canada. The White House has cited fentanyl flowing across the border as a reason for the declaration.
• Some Senate Democrats this week have raised concerns that voting for the resolution would make it look like they are against stopping fentanyl coming in from Canada, multiple sources told Axios.
• Kaine told Axios on Wednesday that he thinks "we're gonna be okay on our side" but the party was working through some internal concerns over the resolution.

The big picture: If Democrats can stick together, they stand a good shot of passing the measure through the Senate on Wednesday evening.

• Kaine has already picked up support from a handful of Senate Republicans, including Sens. Mitch McConnell (R-Ky.), Rand Paul (R-Ky.) and Lisa Murkowski (R-Alaska.). Democrats need at least four Republican "yes" votes.

• Trump is expected to make more tariff announcements Wednesday afternoon ahead of the vote. The president on Tuesday bashed Kaine's proposal and pressured Republicans to vote against it.
• Even if the measure passes the Senate, it would face long odds in the GOP-controlled House.
