You can do that in R using the TCGAbiolinks package (with which you can also download the actual gene expression data as follows) and follow the instructions from the Bioconductor webpage. My script would be as follows:

library("TCGAbiolinks")

DIRPREFIX <- "/PATH/"

## Download raw counts for indicated sets
## Example of TCGA.data.sets: c("TCGA-GBM")
for (id in TCGA.data.sets){
  clin.query <- GDCquery(project = id, data.category = "Clinical")
  json  <- tryCatch(GDCdownload(clin.query), 
                    error = function(e) {GDCdownload(clin.query, method = "client")})
  ## the following types of clinical data can be obtained (just pick whichever you need)
  clinical.drug <- GDCprepare_clinic(clin.query, clinical.info = "drug")
  clinical.admin <- GDCprepare_clinic(clin.query, clinical.info = "admin")
  clinical.radiation <- GDCprepare_clinic(clin.query, clinical.info = "radiation")
  clinical.patient <- GDCprepare_clinic(clin.query, clinical.info = "patient")
  clinical.stage_event <- GDCprepare_clinic(clin.query, clinical.info = "stage_event")
  clinical.new.tumor.event <- GDCprepare_clinic(clin.query, clinical.info = "new_tumor_event")
  clinical.followup <- GDCprepare_clinic(clin.query, clinical.info = "follow_up")
  clinical.index <- GDCquery_clinic(id, type = "clinical")
  clinical.biospecimen <- GDCquery_clinic(id, type = "biospecimen")
  save(WHAT_YOU_NEED, file = file.path(DIRPREFIX, paste0(id, "_clinical.Rdata")), compress = "xz")
}
