With the Missouri GOP Senate primary now less than 40 days away, a new Republican group called Show Me Values began airing its first ad Friday highlighting the several scandals Greitens faced when he served as the state’s governor. CNN’s Michael Warren reports the group is spending more than $1 million on the ads.

A separate outside group, led by former Missouri GOP Sen. John Danforth, is also ramping up its activity, as CNN’s Sara Murray reported this week. Danforth said the super PAC has raised more than $5 million in an effort to recruit an independent candidate into the Missouri Senate race should Greitens win the Republican nomination.

This all came on the heels of the news that John Wood would be leaving his post on the House select committee investigating January 6 this week, which is earlier than expected. Some Missouri Republicans have encouraged Wood, a former clerk for Supreme Court Justice Clarence Thomas who also previously worked for Danforth, to enter the race as an independent conservative alternative.
