(Washington, DC) - South Carolina Senator Lindsey Graham says President Biden is "compromised."
During an interview with CNN's "State of the Union," the Republican said Biden had a disastrous debate last week and a disastrous presidency over the past three years.
He called for investigations into the president's handling of the southern border.
Biden has faced sharp criticism following Thursday night's debate performance, in which he struggled against his political rival Donald Trump.
Some of the president's allies have called on him to step aside to allow the party to select a replacement at the Democratic National Convention.
