The call took place before Russian President Vladimir Putin on Monday offered a three-day truce to coincide with Moscow’s commemorations for the end of World War II.
Rubio said Sunday that this week will be crucial in assessing efforts to end the war, which US President Donald Trump has promised to stop on the first day of his presidency.
In the interview Sunday with NBC News’s “Meet the Press,” Rubio said that there were “reasons to be optimistic, but there are reasons to be realistic as well,” and that the United States could decide to focus on other priorities.
