I do not have complete information, so I cannot determine whether President Trump was confused.
However, different media outlets and political groups are likely to interpret the situation in varying ways.
Networks such as MSNBC and CNN will repeatedly show this footage and raise questions about the President's mental acuity or health. In contrast, Fox News will present this as a positive moment for President Trump, especially among younger Americans, and suggest that Democrats are losing support from youth voters.
Among the general public, some Democratic and liberal individuals will question the President's cognitive state, while conservative will defend him and call the critic “you are Trump hater, you are Trump hater, you are Trump hater”.
