why is a congresswoman buying Hubbell $HUBB like 5 times in 2 weeks

was digging through the congress disclosures and April McClain Delaney (rep from maryland) bought Hubbell $HUBB on 5 separate days back in early june. also grabbed some Entegris $ENTG.

buying the same name 5 times in a row is not normal, usually these congress trades are one and done. HUBB is electrical equipment / grid infrastructure stuff. makes me wonder if theres a data center or grid buildout angle she's seeing, or her advisor just really likes it idk.

the disclosed amounts are the little 1k-15k ranges so cant tell the real size. anyone got a take on Hubbell here? feels like an under the radar name to me
