Elaine Chao is in a powerful position in the Trump administration and is using this role as a way to serve the political and professional interests of herself and her husband. This is a clear conflict of interest and is edging on corruption.
Why is this important?
According to Politico, Chao's Transportation Department has designated a special liaison to help with grant applications and other priorities from her husband Mitch McConnell's state of Kentucky. This has paved the way for grants totaling at least $78 million, at a time when McConnell is preparing to campaign for reelection. Other states do not enjoy this privilege, so this gives a special advantage to projects favored by her husband, which in turn benefits his political interests, all of which is unethical.
