Hello from CNN. I'm Joe Beck with the five things you need to know for Thursday

July 18th. President Joe Biden is self isolating in Delaware after testing

positive for COVID-19 yesterday and it's really bad timing.

He has had to cancel events as he continues to face calls to drop out of the 2024 race

from high profile people in his own party.

Sources say former House Speaker Nancy Pelosi has privately voiced her concerns in a call with

Biden.

CNN's M.J. Lee has more from the White House.

Nancy Pelosi told President Biden that polling shows the president cannot defeat

Donald Trump and that the president would destroy Democrats chances of winning the

House in November if he were to continue seeking a second term. The president

responded, we are told by our sources by being defensive about the

polling and told Pelosi he has seen polling that shows that he can in fact win it is

impossible almost to overstate the importance of Nancy Pelosi.

She is somebody that has incredible sway within her party

and probably has the best pulse of what her colleagues in the House are thinking right now

than almost anybody else.

Ohio Senator JD Vance accepted the Republican nomination for Vice President last night, on the

penultimate day of his party's National Convention.

In a prime time address, Vance introduced himself to the nation as someone who would stand up for the values of America's heartland.

To the people of Middletown, Ohio and all the forgotten communities, in Michigan, Wisconsin, Pennsylvania, and Ohio, and every corner of our nation.

I promise you this.
