Unable to embed CDC websites or pdfs using web objects in Storyline 360

Hello,

I'm having difficulty loading pdfs or websites from the cdc.gov website into Storyline 360... This link for instance is not working when I attempt to use as a web object: vetoviolence.cdc.gov/apps/aces-infographic/

I am curious if anyone else is having this problem and if anyone knows of a work around? I'm trying to keep the learner in the module and prevent opening additional browser windows/tabs. Thank you.
