Republican and Democratic senators called on President Donald Trump on Tuesday to reverse a recent diesel agreement with Russian President Vladimir Putin. Their appeal brings members of Trump’s party together with Democrats in opposition to the arrangement.

The senators’ demand comes against a backdrop of sanctions directed at Russian officials, businesses and financial institutions that help sustain Russia’s war in Ukraine. The supplied material does not establish how the diesel agreement would interact with those measures or specify its terms.

The sanctions legislation was named in memory of the late Republican senator Lindsey Graham, who helped negotiate Trump’s support for the package. That history provides context for the bipartisan challenge: Trump had supported the sanctions legislation, while Republican and Democratic senators are now seeking to have his diesel agreement rescinded.

The supplied excerpts do not identify the senators making the appeal or provide a response from the administration. They also do not specify the volume of diesel covered by the agreement.
