Why Ginni Thomas' texts with Mark Meadows could be "a tricky area" for congressional investigators

There could be more text messages between Supreme Court Justice Clarence Thomas' wife, Virginia "Ginni" Thomas, and Trump White House chief of staff Mark Meadows, CBS News chief election and campaign correspondent Robert Costa told "CBS Mornings." 

"There might very well be texts we have not seen. Twenty-nine were provided to the committee. Twenty-one from Ginni Thomas to Meadows. Eight from Meadows to Ginni Thomas. These were part of a collection of over 2,300 text messages Meadows provided to the committee," said Costa. "But there are gaps. The last text in what we've reported comes in late November 2020. Then there is a stray one about Vice President Pence and the end of America in January of 2021, days after the insurrection. So, this is a story that is beginning, not ending." 

Copies of messages where Ginni Thomas, a longtime conservative activist, repeatedly encouraged Meadows to help overturn the 2020 presidential election were obtained by Costa and Bob Woodward of The Washington Post. They joined "CBS Mornings" to discuss the revelations they uncovered.
