WATCH: White House press secretary Karine Jean-Pierre holds briefing on migrant flights, Ukraine atrocities

For a second day, the White House hammered the Republican governors of Texas and Florida for arranging for the transport of migrants to Democratic strongholds in the Northeast and Mid-Atlantic.

Watch the briefing in the player above.

The governors of Texas and Arizona have sent thousands of migrants on buses to New York, Chicago and Washington, D.C., in recent months.

But the latest surprise moves – which included two flights to Martha’s Vineyard Wednesday paid for by Florida – reached a new level of political theater that critics derided as inhumane.

Florida Gov. Ron DeSantis said the flights to Martha’s Vineyard were part of an effort to “transport illegal immigrants to sanctuary destinations.”

Two buses of migrants from Texas arrived early Thursday outside Harris’ residence at the United States Naval Observatory. The buses carried more than 100 migrants from Colombia, Cuba, Guyana, Nicaragua, Panama and Venezuela.

White House Press Secretary Karine Jean-Pierre spoke to reporters Friday as migrants flown to Martha’s Vineyard on the orders of Florida Gov. Ron DeSantis were being moved Friday to housing on a military base on Cape Cod, Massachusetts.

The White House also weighed in on the latest from Ukraine after President Volodymr Zelenskyy cited evidence of atrocities in a mass burial site that has been found in an area recently freed of Russian occupation.

Zelenskyy said hundreds of people had been found “tortured, shot, killed by shelling” at the site in Izium.

He cited evidence of atrocities such as a body with a rope around its neck and broken arms.

Zelenskyy said more than 400 graves have been found at the site but that the number of victims isn’t yet known. Zelenskyy, who visited the Izium area on Wednesday, said the discoveries showed again the need for world leaders to declare Russia a state sponsor of terrorism.
