This is Democrat Rep. Karen Bass who shows up 20 minutes late. She votes 'AYE' after hearing her Democrat associates vote the same way. She most likely did not hear what the specific vote was on. It turned out to be the impeachment vote.
Abigail Marone posted this on social media, "Wondering how partisan impeachment really is? Here's Democrat @RepKarenBass walking in 20 minutes late, having no idea what the committee is voting on, but saying "I" anyway because she hears all her fellow Democrats voting yes. Democrats are taking this very seriously!"
