The first link has to do with the work of the House Oversight Committee and how much money the Taliban syphons off from US Aid. Yes, the word obstruct is used in tje article, but this isn't in reference to Jordan's impeachment investigation.
The second is in relation to a foreign affairs committee request for details behind the Afghan after action report. Not even an investigation, never mind Jordan's investigation. But again the word obstruction appears.
The third link makes a compelling argument that Hunter Biden committed tax crimes, and uses the lack of a direct link to Joe Biden to intuit that obstruction must be happening. But the lack of evidence is not evidence. If there is an impeachable offense there then have at it. But making an argument to the public is neccessarily one sided. Making an argument in court is very different. I will wait on the court (House investigation) to conclude.
