"Thursday’s statement underlines the fact that his initial statement, which was reportedly dictated by the president in July, was misleading and false. Special counsel Robert Mueller and his team, who are tasked with investigating any potential collusion between the Trump campaign and Russia, are “keenly interested” in the president’s involvement in crafting the statement. This is of interest to the Mueller because Trump may have tried to “corruptly persuade” a witness into giving false testimony, which is a crime."
