Former President Donald Trump has launched a new attack ad targeting Vice President Kamala Harris. The advertisement, which is Trump's largest ad buy of the election, criticizes Harris as 'failed, weak, and dangerously liberal.' The ad focuses on Harris's handling of the border crisis, using her own words to underline the accusations. Harris, who has been criticized in her role as border czar, faces this attack as both she and Trump intensify their campaigns for the upcoming presidential election. The ad was released on Monday.
