Berkshire Hathaway Inc.’s Warren Buffett has been in touch with senior officials in President Joe Biden’s administration in recent days as the regional banking crisis unfolds.

There have been multiple conversations between Biden’s team and Buffett in the past week, according to people familiar with the matter, who asked not to be identified because the information is private. The calls have centered around Buffett possibly investing in the US regional banking sector in some way, but the billionaire has also given advice and guidance more broadly about the current turmoil.
