Former Sen. McCaskill claims 90-year-old Dianne Feinstein being in office is'real damage to her legacy'

Former Senator and colleague Claire McCaskill said 90-year-old Sen. Dianne Feinstein was doing "real damage to her legacy" 

by remaining in office despite the fact that she reportedly lacked the legal authority to do so. 

McCaskill stated Thursday on MSNBC's "Morning Joe" that Feinstein's "extraordinary as a United States senator"

reputation is being damaged by the controversy. 

McCaskill recounted how the late Senator Robert Byrd became a "kind of caricature of what he formerly was" as his age progressed,

 to the point where his staff had to "hold his hand up" for votes in Congress.  

When asked about the court dispute surrounding Feinstein's estate, McCaskill stated, "This whole story makes me incredibly sad." 

McCaskill also brought up the news that Feinstein's daughter is the senator's legal guardian while she is sick.
