"Morning kisses on Joseph's last day of school! We are so excited for the summer!" Trump captioned the photo.

Shortly after Trump exited her home she was seen walking with her hand resting on the back of Joseph's head while her 5-year-old daughter, Arabella Kushner, followed closely behind.

Though Trump was all smiles Wednesday morning, her father's White House is facing steep controversy amid a growing investigation into the relations between the Trump administration, including her husband and White House senior adviser, Jared Kushner, and Kremlin officials.
