Joe Biden for president?

Joe Biden has recently stated that he will be running for the Democratic Party's presidential nomination against, mainly, Hillary Clinton. On Tuesday, Mr. Biden invited hundreds of committee members to a press conference in which he was scheduled to discuss the Iran nuclear deal. The Times reported that two members of this committee thought this was weird, because they had never before been called to a conference call in which the Vice President discussed foreign policy and that they take it as if he wants to be on the political radar before the Democratic party's session on Friday.
