  We present the first analysis of internal coronal mass ejection (CME)
structure observed very close to the Sun by the Wide-field Imager for Solar
PRobe (WISPR) instrument on board Parker Solar Probe (PSP). The transient
studied here is a CME observed during PSP's second perihelion passage on 2019
April 2, when PSP was only 40 R_sun from the Sun. The CME was also well
observed from 1 au by the STEREO-A spacecraft, which tracks the event all the
way from the Sun to 1 au. However, PSP/WISPR observes internal structure not
apparent in the images from 1 au. In particular, two linear features are
observed, one bright and one dark. We model these features as two loops within
the CME flux rope channel. The loops can be interpreted as bundles of field
lines, with the brightness of the bright loop indicative of lots of mass being
loaded into those field lines, and with the dark loop being devoid of such mass
loading. It is possible that these loops are actually representative of two
independent flux rope structures within the overall CME outline.
