Forty-three US senators, many of whom opposed the 2015 nuclear deal with Iran, have called on President Joe Biden to work on an international agreement that addresses issues beyond Tehran's nuclear program, Reuters reported.

“Democrats and Republicans may have tactical differences, but we are united on preventing an Iranian nuclear weapon and addressing the wide range of Iranian behavior,” the senators wrote in a letter to Biden, dated Thursday.

The letter was prepared by Democratic Senator Bob Menendez and Republican Senator Lindsay Graham.

The letter reiterates the argument put forward over the years by opponents of the nuclear deal that any negotiations with Iran must address a wide range of problems.

Menendez, now Senate Foreign Relations Committee chairman, was among Democrats who broke from then-President Barack Obama’s administration to join nearly every congressional Republican in opposing the nuclear agreement, which was also fiercely opposed by Israel.
