Probing Biden family corruption is GOP’s duty to democracy

As a tactical concern, the House GOP’s decision to open an investigation into Biden family corruption is questionable. It promises limited political return. It would serve Republicans, and the country, far better if the House focused on a hyper-politicized Justice Department that targets the political opposition, labels concerned parents “domestic terrorists” and ignores violence aimed at pregnancy centers, for starters.

None of that, however, means there isn’t sufficient circumstantial evidence suggesting President Joe Biden not only lied about knowing his son was favor-trading on the family name with corrupt autocracies...
