Biden says he won't step aside, new details on potential Trump VP pick | LiveNOW from FOX

President Biden doubled down on his refusal to step aside as the Democratic nominee for president amid more calls for him to do so. In an open letter to congressional Democrats, Biden called for an end to the party drama that has made headlines since his poor debate performance.
In the letter, Biden reiterated that he's "firmly committed to staying in this race" and argued that any further questioning of his candidacy "only helps Trump and hurts us."
The debate was a major setback for Biden, who at 81 is the oldest president in the nation's history.
But Biden, in his letter, emphasized, "I want you to know that despite all the speculation in the press and elsewhere, I am firmly committed to staying in this race, to running this race to the end, and to beating Donald Trump."
Meanwhile, a senior adviser for the Trump campaign said that former President Trump is narrowing down candidates for his running mate and is close to making his final decision, perhaps as soon as this week.
Miller added that Trump has many "great choices" and that the final decision could happen any time between now and the Republican convention starting on July 15.
When asked if Sen. Marco Rubio, R-Fla., Sen. JD Vance, R-Ohio, or North Dakota Gov. Doug Burgum are the most serious candidates to be Trump's running mate, Miller said, "President Trump has discussed even more names than that."
LiveNOW's Andrew Craft spoke about Biden, Trump and other political headlines with 24sight's Tom LoBianco.
