It remains doubtful, though, if Olivia Marsdin is an alien, or an alien caught the original POTUS and pretended to be her.

In the meantime, based on the trailer for the next episode of "Supergirl" season 2, named "Distant Sun," a bounty will be put on Kara as she will be captured. While it remains unknown who is back the hunt on Kara, it is presumed that they are no other than Mon-El's (C. Wood) parents as they need their son to return with them.
