Harris in recent months hired Lorraine Voles and Adam Frankel, both of whom served with her transition team, to help with 'organizational development, strategic communications and long-term planning,' a White House official told the Washington Post.
Frankel, who served as a speechwriter for former President Barack Obama, is married to Psaki's sister Stephanie Psaki, a senior adviser at the Department of Health and Human Services.
The new public relations hires come as Harris, who is seen as likely to attempt the Democratic presidential nomination, faces falling approval ratings and criticism over her handling of the border.
President Joe Biden has handed Harris several complex and politically charged projects, including addressing the root causes of a surge in illegal border crossings, and spearheading a dispute over US election laws.
These assignments have reportedly frustrated members of Harris' inner circle, who see them as political hot-potatoes with no easy wins, possibly hurting the vice president's further political ambitions.
Harris' approval ratings turned cold shortly after her controversial trip to Mexico and Guatemala on June 8, according to a Los Angeles Times analysis of polling data.
The trip to address the so-called 'root causes' of migration came as illegal crossings at the southern US border neared a 20-year high, and Harris raged back then when asked why she had not yet visited the border itself.
Biden's approval ratings further started to sink around the same time, and have slipped further since, so it's unclear whether Harris hurt from a general decline in satisfaction with the administration.
In the past week, border matters have been thrust back into the limelight, as a squalid camp of Haitian migrants in Del Rio, Texas grew to 15,000 last weekend.
On Friday, Homeland Security Secretary Alejandro Mayorkas announced that almost 30,000 Haitian migrants have been encountered attempting to enter the nation illegally since September 9.
He announced that 2,000 have been expelled on 17 flights, 8,000 have returned to Haiti voluntarily, 12,400 have been freed into the US and 5,000 are being processed.
That leaves 2,600 missing. Officials have explained that some have crossed back into Mexico, where they may try to enter the US again.
The camp in Del Rio has now been cleared, though new reports show that 19,000 migrants, who are mostly Haitian, are congregating in northern Colombia with plans to journey to the Texas crossing.
