While House GOP leader Kevin McCarthy and other Republicans vowed to investigate the Department of Justice over the search, Vice President Mike Pence issued a tweet expressing his "concern" over the incident.

"I share the deep concern of millions of Americans over the unprecedented search of the personal residence of President Trump," Pence tweeted.

Pence, who like Trump is considering a 2024 presidential run, also tweeted that some FBI agents "were found to be acting on political motivation" during the Trump administration.

In what looked a carefully worded series of tweets, Pence tweeted that Attorney General Merrick Garland "must give a full accounting to the American people as to why this action was taken and he must do so immediately."
