Mark 1:12 ‘The Spirit immediately drove him into the wilderness.’

This verse indicates that Jesus’ temptation happened ‘immediately’ after his baptism.

For Ehrman (Jesus, Interrupted) this is a problem:

In John there is no account of Jesus being tempted by the Devil in the wilderness. The day after John the Baptist has borne witness to the Spirit descending on Jesus as a dove at baptism (John 1:29–34), he sees Jesus again and declares him to be the Lamb of God (John is explicit, stating that this occurred “the next day”). Jesus then starts gathering his disciples around him (1:35–52) and launches into his public ministry by performing his miracle of turning water into wine (2:1–11). So where was Jesus the next day? It depends on which Gospel you read.

But this is careless reading of the text.  According to Blomberg (Historical Reliability)

‘because verses 19-28 refer to an incident in John’s ministry that could have happened before or after Jesus’ baptism, we have no way of securely correlating this information with the synoptic portrait (or of corroborating claims of contradiction). Verses 29b-34 read most naturally, however, as the Baptist’s after-the-fact reflection on Jesus’ baptism, suggesting that all of John’s episodes about the Baptist may have occurred after that event, and thus after Jesus’ temptations as well (cf. Mark 1:12-13 pars.).’
