Holy crap. Now Sessions. The stories just keep coming out.
What do you think is going on here, seriously?
Senators speak to the ambassadors of various nations, particularly the more powerful ones, as whatever committee they are on interacts with their foreign counterparts.
For example Senators and House critters on a committee overseeing social security will meet with the UK, Japanese, German, French, Russian, Chinese, etc counterparts to discuss how they are going to exchange social security payments by foreign nationals here from those countries, and vice versa. These meetings are generally assisted in being set up by th e ambassadors of that nation.
This is just more smoke and dust being kicked up by the Dimmocrats to keep people from seeing through their shenanigans, nothing more.
