Wow there's a lot of "Ick" in this thread.
OP hasn't given us much information about Abedin's allegations. A quick search pulled up a story about her memoir and a brief quote about the incident... sounds like she was in her 20s (senators have to be at least 30, but obviously could be much older), he invited her in for a coffee, "“Then, in an instant, it all changed. He plopped down to my right, put his left arm around my shoulder, and kissed me, pushing his tongue into my mouth, pressing me back on the sofa[.]” She then says something about wishing in the moment that she could erase that 10 seconds from her memory.
I suspect she's being a bit euphemistic and she's leaving something out. Be honest, you're sticking your tongue down a woman's throat for 10 seconds and you're not touching her breasts or ass? The minute an intimate part of the body is involved that starts sounding like indecent assault at the very least.
Unless this scenario sounds like you on a Saturday Night ("[he/she] seems interested, time to jump on [him/her] and shove my tongue into [his/her] mouth") you're probably in the clear. If you're something other than a hormone-riddled teenager maybe save the freedom kisses for lip contact two or three.
As for Abedin, it's a story she's telling about her life. Something that happened a long time ago. There's no threat of legal action involved. The "Social Injustice Warriors" can calm the fuck down.
