A group of 140 bipartisan members of the House is urging President Biden to seek a more "comprehensive" agreement with Iran, which means the group of lawmakers opposes a revival of the original 2015 nuclear deal, known as the JCPOA.

In a letter sent to Secretary of State Antony Blinken, 70 Democrats and 70 Republicans said President Biden "must seek an agreement or set of agreements with Iran that are comprehensive in nature to address the full range of threats that Iran poses to the region."

"As Democrats and Republicans from across the political spectrum, we are united in preventing an Iranian nuclear weapon and addressing the wide range of illicit Iranian behavior," the letter reads. The effort was organized by Reps. Anthony Brown (D-MD) and Michael Waltz (R-FL).

Seeking a stronger agreement before the US gives Iran sanctions relief and returns to the JCPOA would be a non-starter for negotiations with Tehran. Iranian officials have been clear that they want the deal that they signed in 2015 and have been working to preserve since the Trump administration withdrew from it in 2018.
