ABC News hosted a broadcast of “This Week” on Sunday, July 12, 2026 [1], featuring tributes to the late Sen. Lindsey Graham.

The program highlighted a shift in the U.S. political landscape following the death of the senator while addressing volatile international security issues.

Sen. Tim Scott (R-SC) joined host George Stephanopoulos to honor his former colleague. "We mourn the loss of Senator Lindsey Graham, a friend and a colleague," Scott said [2]. The tribute segment began at the 1:20 mark of the broadcast [2].

Beyond the memorial, the program focused on the status of nuclear negotiations with Iran. UN Ambassador Mike Waltz said the United States must remain engaged because the Iran negotiations are at a critical juncture [2].

Rep. Michael McCaul (R-TX) also appeared on the program to discuss a recent delegation to Eastern Europe. McCaul said a recent visit to Ukraine reaffirmed the commitment of the U.S. to supporting the Ukrainian people [2].

Sen. Chris Coons (D-DE) participated in the discussions, contributing to the analysis of U.S. policy in Ukraine and the Middle East. The broadcast served as a forum for both parties to reflect on the loss of Graham and the current state of global diplomacy [1, 2].

“"We mourn the loss of Senator Lindsey Graham, a friend and a colleague."”

The intersection of a high-profile legislative vacancy and active nuclear negotiations suggests a period of transition for U.S. foreign policy. The loss of a senior senator often triggers shifts in committee leadership and diplomatic influence, occurring here simultaneously with critical deadlines in Iran and ongoing military support for Ukraine.
