This is a lie.
VP Harris was never "in charge" of the border, but what is factual is that you and Trump killed the strongest bipartisan bill in recent history to secure our border because you wanted to exploit this issue for your campaign instead of solving it.
Joe Biden put Kamala Harris in charge of the southern border and then we saw the worst invasion of illegals in American history. Kamala failed to secure the border and American citizens paid the price.
