  Two charged pion final states are studied for GeV photons incident on
protons. The data come from Thomas Jefferson National Accelerator Facility
using the CLAS detector. A tagged photon beam of 0.5-2.4 GeV/c was produced
through bremsstrahlung radiation and was incident on a liquid H2 target. This
analysis looks at the reaction $\gamma p \to p \pi^+ \pi^-$ using a partial
wave analyis to identify intermediate baryon resonances. Total cross section is
compared to previous experiments and preliminary differential cross sections
for intermediate baryon resonance quantum numbers are shown.
