President Trump risks squandering the momentum he has gained from some good news in the last week, according to both Republican strategists and independent observers.

In a Friday interview on Fox News Channel, Trump renewed his assault on the Justice Department’s special counsel Robert Mueller, who is investigating allegations of cooperation between Trump’s presidential campaign and Russia.

The day before, Trump made an embarrassing climbdown, admitting that his earlier suggestion that he had taped conversations with fired FBI director James Comey was untrue.
