President Donald Trump's campaign is blasting Joe Biden's vice presidential pick, calling Sen. Kamala Harris ``phony.''

In a statement, Trump adviser Katrina Pierson says Harris ``will abandon her own morals, as well as try to bury her record as a prosecutor, in order to appease the anti-police extremists controlling the Democrat Party.''

Pierson says Harris has ``gleefully embraced the left's radical manifesto, calling for trillions of dollars in new taxes and backing Bernie Sanders' government takeover of healthcare.''

Pierson calls Harris ``proof that Joe Biden is an empty shell being filled with the extreme agenda of the radicals on the left.''

For weeks, Trump's campaign promised an aggressive response against whomever was selected by Biden as his running mate.

Says Pierson, ``At the ballot box, Americans will resoundingly reject the abysmal failures of Biden-Harris in favor of the America First strength of President Donald Trump and Vice President Mike Pence.''
